Subject: [PATCH] lvconvert: no validation for thin-pools not used by lvm2

lvm2 supports thin-pool to be later used by other tools doing

virtual volumes themself (i.e. docker) - in this case we

shall not validate transaction Id - is this is used by

other tools and lvm2 keeps value 0 - so the transationId

validation need to be skipped in this case.

(cherry picked from commit 1316cafbe988307264e4f87dbcffaf56bc2ab388)
