find_first_zero_bit()'s parameter 'size' is defined in bits,
not in bytes.

Calling find_first_zero_bit() with the wrong size unit
will lead to insidious bugs.

Fix all uses of find_first_zero_bit() called with
sizeof() as size argument in drivers/pci.

Also had to fix broken error handling in pci_epc_epf_link()
in order to do proper error handling for find_first_zero_bit().
