[linux-lvm] bug in lvmlockd

[Andrey Staselko]

If lvm configured with --enable-lockd-dlm and without --enable-lockd-sanlock,
then "lvmlockd --adopt 1" always produces error "adopt_locks failed, reset host" in adopt_locks().

lm_get_lockspaces_sanlock() stub in daemons/lvmlockd/lvmlockd-internal.h line 577 returns -1,
that breaks the adopt_locks() function in daemons/lvmlockd/lvmlockd-core.c line 5160:
        
	rv = lm_get_lockspaces_sanlock(&ls_found);
	if ((rv < 0) && (rv != -ECONNREFUSED))
		goto fail;
