Fix that by allocating the structs on heap. Cleanup some formatting issues in the code around these changes and fix incorrect data type uses of returned functions in a couple places.

Consider the following flow ice_add_vlan(hw, ) Where we add three VLAN filters for VIDs 7, 8, and 9, all for VSI 0. The ice_add_vlan will create a single vsi_list and share it among all the filters. Later, if we try to remove a VLAN, ice_remove_vlan(hw, ) Then the removal code will update the vsi_list and remove VSI 0 from it. But, since the vsi_list is shared, this breaks the list for the other users who reference it. We actually even free the VSI list memory, and may result in segmentation faults. This is due to the way that VLAN rule share VSI lists with reference counts, and is caused because we call ice_rem_update_vsi_list even when the ref_cnt is greater than one. To fix this, handle the case where ref_cnt is greater than one separately. In this case, we need to remove the associated rule without modifying the vsi_list, since it is currently being referenced by another rule. Instead, we just need to decrement the VSI list ref_cnt. The case for handling sharing of VSI lists with multiple VSIs is not currently supported by this code. No such rules will be created today, and this code will require changes if/when such code is added.

In initialization we associate the control queue interrupts with the pf->hw_oicr_idx and enable the interrupts by setting the CAUSE_ENA bit. The problem comes on teardown because we are not clearing the CAUSE_ENA bit for the control queues, but the vector at pf->hw_oicr_idx (miscellaneous interrupt vector) gets disabled. Fix this by clearing the CAUSE_ENA bit in the appropriate control queue registers on when freeing the miscellaneous interrupt vector. Also, move the call to ice_free_irq_msix_misc() to after ice_deinit_sw() in ice_remove() because ice_deinit_sw() makes an AQ call, but ice_free_irq_msix_misc() disables the miscellaneous vector and it's associated interrupts. Also, create two small helper functions to enable and disable the control queue interrupts respectively.

Unfortunately, on devices controlled by ice, this register is NOT cleared on reset. This causes the VF to miss resets, and even on properly-announced resets, the VF driver complains that it didn't see the reset. To fix this, we'll do it in software. When we handle a VF reset (whether triggered by software or VFLR), clear this register after the HW reset is complete.
