qede: Fix multicast mac configuration

BugLink: https://bugs.launchpad.net/bugs/1860490
[ Upstream commit 0af67e49b018e7280a4227bfe7b6005bc9d3e442 ]

Driver doesn't accommodate the configuration for max number
of multicast mac addresses, in such particular case it leaves
the device with improper/invalid multicast configuration state,
causing connectivity issues (in lacp bonding like scenarios).
