net: ethernet: adi: adin1110: Fix multicast offloading

[ Upstream commit 8a4f6d023221c4b052ddfa1db48b27871bad6e96 ]

Driver marked broadcast/multicast frames as offloaded incorrectly.
Mark them as offloaded only when HW offloading has been enabled.
This should happen only for ADIN2111 when both ports are bridged
by the software.
