[lvm-devel] [PATCH 03/22] Skip check missing rem.VGs for non-activate locks

[Zdenek Kabelac]

Skip call for checking whether this LV needs to locks some
more remote VGs (applies to replicator_dev devices).

The effect is, that deactivation of replicator-dev devices does
not require to take a lock for remote VGs, so avoids repeated invoke
of deactivate_lv.
