[PATCHv2 0/2] introduce get_task_exe_file and use it to fix audit_exe_compare

audit_exe_compare directly accesses mm->exe_file without making sure the object is stable. Fixing it using current primitives results in partially duplicating what proc_exe_link is doing. As such, introduce a trivial helper which can be used in both places and fix the func.
