net: dsa: remove the transactional logic from MDB entries
For many drivers, the .port_mdb_prepare callback was not a good opportunity to avoid any error condition, and they would suppress errors found during the actual commit phase. Where a logical separation between the prepare and the commit phase existed, the function that used to implement the .port_mdb_prepare callback still exists, but now it is called directly from .port_mdb_add, which was modified to return an int code.
