Fix ix(4) link status

[Gerhard Roth]

ix(4) relies on link-state change interrupts the update the link state
via if_link_state_change(). However, after ixgbe_stop() all interrupts
for the device are disabled and there won't be any IXGBE_EICR_LSC
interrupt.

Simple solution: manually update link state after ixgbe_stop().
