Subject: [PATCH] lvcreate: %FREE -> %PVS

This is hotfix for RHBZ: https://bugzilla.redhat.com/1324537
However already the %FREE is not a good fit and we need something
better. Meanwhile make  -l%PVS work at least as good as %FREE
for thin-pool.

TODO: this needs rework - it should be allocator to do all the size
decisions at one place.
