core timer: don't hang when the clock goes back.

If the clock shifts back, don't hang in a loop of running
process_masterspan from the timer interrupt forever.

Fixes a regression of r9407.

After talking with Tzafrir on IRC, I combined the check if your far ahead
with the check if you're behind and added a '\n' at the end of the
existing "detected time shift" message.  That is why this patch is
different than what is posted on issue #19035.
