signal/parisc: Use force_sig_mceerr where appropriate

In do_page_fault where an mceerr is generated stop and call force_sig_mceerr.
Keeping the mcerr handling logic out of the force_sig_info call below.

This ensures that only and always in the mcerr case is lsb interesting.

This ensures setting set si_lsb in the future won't accidentally
stomp another siginfo field in the non mcerr case.
