ionic: catch failure from devlink_alloc
[ Upstream commit 4a54903ff68ddb33b6463c94b4eb37fc584ef760 ]
Add a check for NULL on the alloc return. If devlink_alloc() fails and
we try to use devlink_priv() on the NULL return, the kernel gets very
unhappy and panics. With this fix, the driver load will still fail,
but at least it won't panic the kernel.
