Due to an invalid conflict resolution on my side while working on 2
different series (LAG FDBs and FDB isolation), dsa_switch_do_lag_fdb_add()
does not store the database associated with a dsa_mac_addr structure.
So after adding an FDB entry associated with a LAG, dsa_mac_addr_find()
fails to find it while deleting it, because &a->db is zeroized memory
for all stored FDB entries of lag->fdbs, and dsa_switch_do_lag_fdb_del()
returns -ENOENT rather than deleting the entry.
Fixes: c26933639b54 ("net: dsa: request drivers to perform FDB isolation")
