timers: Get rid of del_singleshot_timer_sync()
del_singleshot_timer_sync() used to be an optimization for deleting timers
which are not rearmed from the timer callback function.
This optimization turned out to be broken and got mapped to
del_timer_sync() about 17 years ago.
Get rid of the undocumented indirection and use del_timer_sync() directly.
No functional change.
