[PATCH] libertas: keep mesh autostart enabled while asleep 



After loading the firmware, mesh autostart will be disabled. After that, the
user will still be able to enable or disable it at will. On suspend, it will be
always activated and later on resume it will go back to the state it had before
going to sleep.
