x86, mce: rename static variables around trigger
"trigger" is not straight forward name for valiable that holds name of user mode helper program which triggered by machine check events. This patch renames this valiable and kins to more recognizable names. trigger => mce_helper trigger_argv => mce_helper_argv notify_user => mce_need_notify No functional changes.
