net: dsa: qca8k: fix broken search_and_del
On deleting an MDB entry for a port, fdb_search_and_del is used. An FDB entry can't be modified so it needs to be deleted and readded again with the new portmap (and the port deleted as requested) We use the SEARCH operator to search the entry to edit by vid and mac address and then we check the aging if we actually found an entry. Currently the code suffer from a bug where the searched fdb entry is never read again with the found values (if found) resulting in the code always returning -EINVAL as aging was always 0. Fix this by correctly read the fdb entry after it was searched.
