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.

Looks good. Except trivial warning that test bot found.
