[Intel-wired-lan] [next PATCH S49-V2 15/15] i40evf: avoid an extra msleep while

[Bimmy Pujari]

From: Jacob Keller <jacob.e.keller at intel.com>

Remove the second call to msleep outside the loop, and move the msleep
within the loop as the first step. This guarantees that a single loop
will wait the minimum time first, and then after the reset finishes we
no longer need an extra msleep.
