net: lan966x: remove guards against !BRIDGE_VLAN_INFO_BRENTRY

Since commit 3116ad0 ("net: bridge: vlan: don't notify to switchdev
master VLANs without BRENTRY flag"), the bridge no longer emits
switchdev notifiers for VLANs that don't have the
BRIDGE_VLAN_INFO_BRENTRY flag, so these checks are dead code.
Remove them.
