Juergen Gross 4e0d26b22e xen/netback: set default upper limit of tx/rx queues to 8 ...

[ Upstream commit 56dd5af9bc ]

The default for the maximum number of tx/rx queues of one interface is
the number of cpus of the system today. As each queue pair reserves 512
grant pages this default consumes a ridiculous number of grants for
large guests.

Limit the queue number to 8 as default. This value can be modified
via a module parameter if required.
