Handle lack of DSM slots in parallel btree build, take 2. Commit 74618e77 added a new check intended to fix a bug, but put it in the wrong place so that parallel btree build was always disabled. Do the check after we've actually tried to create a DSM segment. Back-patch to 11, like the earlier commit.
