From: Jisheng Zhang <Jisheng.Zhang@xxxxxxxxxxxxx>
[ Upstream commit d484e06e25ebb937d841dac02ac1fe76ec7d4ddd ]
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: dc35a10f68d3 ("net: mvneta: bm: add support for hardware buffer management")
