This patch switch to use kvmalloc_array() for using a vmalloc()

ring sizes.

I don't see this as a bugfix - it's more of an enhancement.
Do we need this in net or can we defer this to net-next?
Consider they are users of tx_queue_len of more than 1000000 from google
searching. We'd better have this in -net.
Thanks
I'm not sure myself. For now
