net/mlx5: Bridge, fix ageing of peer FDB entries

Browse Source 
[ Upstream commit da0c52426c ]

SWITCHDEV_FDB_ADD_TO_BRIDGE event handler that updates FDB entry 'lastuse'
field is only executed for eswitch that owns the entry. However, if peer
entry processed packets at least once it will have hardware counter 'used'
value greater than entry 'lastuse' from that point on, which will cause FDB
entry not being aged out.

Process the event on all eswitch instances.
