__mutex_lock_common: use signal_pending_state()
Change __mutex_lock_common() to use signal_pending_state() for the sake of
the code re-use.
This adds 7 bytes to kernel/mutex.o, but afaics only because gcc isn't smart
enough.
(btw, uninlining of __mutex_lock_common() shrinks .text from 2722 to 1542,
perhaps it is worth doing).
