msm: restart: clear the restart reason when the cmd makes no sense

Browse Source 
* This principally was identified when the R recovery started
  issuing reboot commands such as "userrequested,recovery" or
  "userrequested,fastboot". While it's not 100% clear that
  userrequested is supposed to be followed by a reboot *source* as
  opposed to a target, it illuminated the fact that our kernel gets
  stuck rebooting to the same target/reason when an unknown command
  is issued.
* It seems much more logical to normal people that the kernel go ahead
  and reboot to the "normal" (read: Android system) target when the
  one passed to the kernel isn't known, as opposed to getting stuck
  in something like recovery forever.
