xen/netfront: add netconsole support.
add polling interface to xen-netfront device to support netconsole This patch also alters the spin_lock usage to use irqsave variant. Documentation/networking/netdevices.txt states that start_xmit can be called with interrupts disabled by netconsole and therefore using the irqsave/restore locking in this function is looks correct.
