bnxt_en: Wait for FLR to complete during probe

bnxt_en: Wait for FLR to complete during probe

[ Upstream commit 3c1069fa42872f95cf3c6fedf80723d391e12d57 ]

The first message to firmware may fail if the device is undergoing FLR.
The driver has some recovery logic for this failure scenario but we must
wait 100 msec for FLR to complete before proceeding.  Otherwise the
recovery will always fail.
