smh 8d975f8d73 Fix mps deadlock when handling panic
During shutdown mps waits for its SSU requests to complete however when
performing a reboot after handling a panic the scheduler is stopped so
getmicrotime which is used can be non-functional.

Switch to using the same method as shutdown_panic to ensure we actually
complete.

In addition reduce the timeout when RB_NOSYNC is set in howto as we expect
this to fail.
