ixgbe: Do not attempt to perform interrupts in netpoll when down
This patch resolves issues seen when running netconsole and rebooting via reboot -f. The issue was due to the fact that we were attempting to perform interrupt actions when the q_vectors and rings had already been freed via the ixgbe_shutdown routines.
