lvextend: fix overprovisioning check for thin lvs

18722dfdf4d3 lvresize: restructure code
mistakenly changed the overprovisioning check from applying
to all lv_is_thin_type lvs to only lv_is_thin_pool lvs, so
it no longer applied when extending thin lvs.  The result
was missing warning messages when extending thin lvs.

(cherry picked from commit 4baef0f93f608403b6f2db445e7bf1e80f8f3ee6)
