Changes in v2:
- Replace param_get_int to param_get_uint.
- Use '%u' for unsigned int when print.
- Replace EINVAL to ERANGE when out of range [0-CPUs
Should not allocate xen vif queues number more than online cpus.

Yes you are right, you catch my fault again :)
Thanks so much, will resend new later.

We need to take care sysfs too, please ignore this patch, I'll create

Currently xen vnic allowed to create lots of queues by set module param
max_queues(both netback and netfront), when queues number larger than
cpu number, it does not help for performance but need more cpu time.
This patchset limit netback and netfront max queues number to online
cpus number.

Sometimes xennet_create_queues() may failed to created all requested
queues, we need to update num_queues to real created to avoid NULL
pointer dereference.
