[hermon] Ensure hardware is quiescent when no interfaces are open
WinPE has been observed to call PXENV_UNDI_SHUTDOWN but not
PXENV_STOP_UNDI. This means that Hermon hardware is left partially
active (firmware running and one event queue mapped) when WinPE starts
up, which can cause a Blue Screen of Death.
Fix by ensuring that the hardware is left quiescent (with the firmware
stopped) when no interfaces are open.
