From: Mitch Williams <mitch.a.williams@intel.com>

Upon module remove, wait a little longer after requesting a reset before
checking to see if the firmware responded. This change prevents double
resets when the firmware is busy.

Testing Hints: Load and unload VF driver repeatedly
with a lot of VFs enabled and make sure it reinitializes properly each
time.
