genirq: Correctly annotate implicit fall through 

There is a plan to build the kernel with -Wimplicit-fallthrough. The
fallthrough in __handle_irq_event_percpu() has a fallthrough annotation
which is followed by an additional comment and is not recognized by GCC.

Separate the 'fall through' and the rest of the comment with a dash so the
regular expression used by GCC matches.
