From: Colin Ian King <colin.k...@canonical.com>
In the case where the call to dev_alloc_name fails the current exit
path is via err_free_netdev and this calls free_netdev on a null priv
pointer, hence causing a null pointer dereference. Fix this by instead
exiting via err_release_irq.
Detected by CoverityScan, CID#1467844 ("Explitic null dereferenced")

extra-repository")
