In the slavio timer devcie, the ptimer TimerContext::timer is
always created by slavio_timer_init(), so there's no need to
check it for NULL; remove the single unneeded NULL check.

This will be useful to avoid compiler/Coverity errors when
a subsequent change adds a use of t->timer before the location
we currently do the NULL check.
