[ Upstream commit e0243e1966592859da4c6ffe6d43e1576ec3c457 ]

We should be using the multicast sync routines for the multicast
filters.  Also, let's just flatten the logic a bit and pull
the small unicast routine back into ionic_set_rx_mode().

Fixes: 1800eee16676 ("net: ionic: Replace in_interrupt() usage.")
