ionic: Reset LIF device while restarting LIF

Recovery from broken states can be hard.  If the LIF reset in
the fw_down path didn't work because the PCI link was broken,
the FW won't be in the right state for proper restart.  We can
fire another LIF reset in the fw_up path to be sure things
are clean on restart.
