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.
