Subject: [PATCH net-next] team: Remove NULL check before dev_{put, hold}

The call netdev_{put, hold} of dev_{put, hold} will check NULL,
so there is no need to check before using dev_{put, hold},
remove it to silence the warning:

./drivers/net/team/team.c:2325:3-10: WARNING: NULL check before dev_{put, hold} functions is not needed.

Reported-by: Abaci Robot <abaci@...ux.alibaba.com>
Closes: https://bugzilla.openanolis.cn/show_bug.cgi?id=5991
Signed-off-by: Yang Li <yang.lee@...ux.alibaba.com>
