net: mvneta: Fix err code path of probe

Fix below issues in err code path of probe:
1. we don't need to unregister_netdev() because the netdev isn't
registered.
2. when register_netdev() fails, we also need to destroy bm pool for
HWBM case.

Fixes: dc35a10f68 ("net: mvneta: bm: add support for hardware buffer management")
