[patch net] switchdev: fix return value of switchdev_port_fdb_dump in case of error

From: Jiri Pirko <redacted>

switchdev_port_fdb_dump is used as .ndo_fdb_dump. Its return value is
idx, so we cannot return errval.

Fixes: 45d4122ca7cd ("switchdev: add support for fdb add/del/dump via switchdev_port_obj ops.")
