net: graceful exit from netif_alloc_netdev_queues()
[ Upstream commit d339727c2b1a10f25e6636670ab6e1841170e328 ]
User space can crash kernel with
ip link add ifb10 numtxqueues 100000 type ifb
We must replace a BUG_ON() by proper test and return -EINVAL for
crazy values.
Fixes: 60877a32bce00 ("net: allow large number of tx queues")
