ARM: signal: Mark expected switch fall-through

Mark switch cases where we are expecting to fall through. This patch fixes the following warning: arch/arm/kernel/signal.c: In function 'do_signal': arch/arm/kernel/signal.c:598:12: warning: this statement may fall through [-Wimplicit-fallthrough=] restart -= 2; ~~~~~~~~^~~~ arch/arm/kernel/signal.c:599:3: note: here case -ERESTARTNOHAND: ^~~~
