igb/igbvf: don't give up
The driver shouldn't just give up if it fails to get the hardware
mailbox lock. This can happen in a situation where the PF-VF
communication channel is heavily loaded and causes complete
communications failure between the PF and VF drivers.
Add a counter and a delay. The driver will now retry ten times, waiting
one millisecond between retries.
