lvconvert: use LV_TEMPORARY when necessary during lvconvert to thin pool

Browse Source 
This is an addition to original patch for lvcreate - commit 039bdad.
The same principle applies to lvconvert where there are several steps
during which we need to wipe the existing LV that's being converted
to thin pool, making sure there's no other interference from outside (udev).
