YueHaibing f60d53ef57 failover: Add missing check to validate 'slave_dev' in net_failover_slave_unregister ...

[ Upstream commit 9e7e6cabf3 ]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/net/net_failover.c: In function 'net_failover_slave_unregister':
drivers/net/net_failover.c:598:35: warning:
 variable 'primary_dev' set but not used [-Wunused-but-set-variable]

There should check the validity of 'slave_dev'.

Fixes: cfc80d9a11 ("net: Introduce net_failover driver")
