[Intel-wired-lan] [next PATCH S31 v4 06/12] i40evf: Add longer wait after remove module

From: Mitch Williams <mitch.a.williams at 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
