timers: Unconditionally check deferrable base 

commit ed4bbf7910 upstream.

When the timer base is checked for expired timers then the deferrable base
must be checked as well. This was missed when making the deferrable base
independent of base::nohz_active.

Fixes: ced6d5c11d ("timers: Use deferrable base independent of base::nohz_active")
