igc: correctly update RCTL when changing multicast filters.

Fix clearing of bits in RCTL for the non-bpf/non-allmulti case.
Update RCTL after modifying the multicast filter registers as per
the Linux driver.

This fixes LACP on igc interfaces, where incoming LACP multicasti
control packets were being dropped.
