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.

mm: introduce get_task_exe_file
audit: fix exe_file access in audit_exe_compare
