kernel: refactor: shorten has_pending_signals

Browse source

In has_pending_signals there was a switch/case used for optimizations. 
However, today's compilers perform loop unrolling efficiently, thus it is
not needed anymore.

Put i inside the for declaration so we do not risk its escape from the
scope.  Moreover, i starts now from 0 and counts up, as it is a more usual
pattern.
