Mark Johnston 8b3c4231ab posix timers: Check for overflow when converting to ns 
Disallow a time or timer period value when the conversion to nanoseconds
would overflow.  Otherwise it is possible to trigger a divison by zero
in realtime_expire_l(), where we compute the number of overruns by
dividing by the timer interval.

Fixes:	7995dae9 ("posix timers: Improve the overrun calculation")
