mlxsw: spectrum_switchdev: Flush port from MDB entries according to FID index
Currently, flushing port from all MDB entries is done when the last VLAN
is removed. This behavior is inaccurate, as port can be removed while there
is another port which uses the same VLAN, in such case, this is not the
last port which uses this VLAN and removed, but this port is supposed to be
removed from the MDB entries.
Flush the port from MDB when it is removed, regardless the state of other
ports. Flush only the MDB entries which are relevant for the same FID
index.
