iwlagn: fix minimum number of queues setting

Browse Source 
We need to provide a reasonable minimum that will result in a
working setup if used. Set minimum to be 10 to provide for
4 standard TX queues + 1 command queue + 2 (unused) HCCA queues +
4 HT queues (one per AC).

We allow the user to change the number of queues used via a module
parameter and use this minimum value to check if it is valid. Without
this patch a user can select a value for the number of queues that
will result in a failing setup.
