ibmvnic: Refresh device multicast list after reset

Browse Source 
[ Upstream commit be32a24372cf162e825332da1a7ccef058d4f20b ]

It was observed that multicast packets were no longer received after
a device reset.  The fix is to resend the current multicast list to
the backing device after recovery.
