bnxt_en: Wait for FLR to complete during probe 

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.

Fixes: ba02629ff6 ("bnxt_en: log firmware status on firmware init failure")
