x86, mce: use force_sig_info to kill process in machine check
Impact: bug fix (with tolerant == 3)
do_exit cannot be called directly from the exception handler because
it can sleep and the exception handler runs on the exception stack.
Use force_sig() instead.
Based on a earlier patch by Ying Huang who debugged the problem.
