signal/x86: Move MCE error reporting out of force_sig_info_fault

Browse source

Only the call from do_sigbus will send SIGBUS due to a memory machine
check error.  Consolidate all of the machine check signal generation
code in do_sigbus and remove the now unnecessary fault parameter from
force_sig_info_fault.

Explicitly use the now constant si_code BUS_ADRERR in the call
to force_sig_info_fault from do_sigbus.

This makes the code in arch/x86/mm/fault.c easier to follower and
simpler to maintain.
