ixgbevf: introduce delay for checking VFLINKS on 82599



VFLINKS.LINKUP bit tends to flap when a DA or SFP+ cable is disconnected.
It can take up to 500 usecs for the LINKUP bit to be correct.

This patch resolves the issue by introducing a delay for 82599 VFs of at
least 500 usecs to make sure the VFLINKS value is correct.
