 #!CommitTicketReference repository=""
 Keep the fetch thread busyobj pointer-ref separate from the client thread
 pointer-ref, and deref it on thread scheduling failure.

 The code tried to deref the same pointer twice, which failed because
 the VBO_DerefBusyobj() will clear the pointer when called. Separating
 allows calling VBO_DerefBusyobj() for each of them.

 Fixes: #1628
 (cherry picked from commit 7746e30e2c53cf55f0f2525bb3f49c9ee83e9611)
