autofs-5.1.1 - fix left mount count return from umount_multi_triggers()

From: Xu Wang <xuw@redhat.com>

If a umount of an NFS mount at the root of a multi-mount fails
umount_multi_triggers() will return an zero (success) when it should
return 1 (a fail). In this case do_expire_direct() will close the
me->ioctlfd fd used for expires stopping further expires of the
direct mount.
