[PATCH 5.10 115/717] ionic: use mc sync for multicast filters

Greg Kroah-Hartman

From: Shannon Nelson <snelson@pensando.io>

[ 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.")
