microblaze: don't reimplement force_sigsegv()
Instead of open coding the sequence from force_sigsegv() just call it.
This also fixes a bug because we were modifying ka->sa.sa_handler (which
is a copy of sighand->action[]), whereas the intention of the code was to
modify sighand->action[] directly.
As the original code was working with a copy it had no effect on signal
delivery.
