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.
