m68k: Don't lose state if sigframe setup fails
If we'd failed in setup_frame(), we've no place to store
the original sigmask. It's not an unrecoverable situation -
we raise SIGSEGV, but that SIGSEGV might be successfully
handled (e.g. on altstack). In that case we really don't
want sa_mask of original signal permanently slapped on
the set of blocked signals.
Standard solution: have setup_frame()/setup_rt_frame()
report failure and don't mess with the signal-related
state if that has happened...
