[PATCH 1/2] misc: Remove if (timer_pending) stop_timer idiom from the code

[Holger Hans Peter Freyther]

osmo_timer_del is an idempotent operation. There is no requirement
to check if it is running. If you don't want a timer to run, delete
it. Maybe one should have called the method _unschedule, _cancel to
make this more clear.
