Coly Li f11ba9df8e bcache: destroy dc->writeback_write_wq if failed to create dc->writeback_thread

commit f54d801dda upstream.

Commit 9baf30972b ("bcache: fix for gc and write-back race") added a
new work queue dc->writeback_write_wq, but forgot to destroy it in the
error condition when creating dc->writeback_thread failed.

This patch destroys dc->writeback_write_wq if kthread_create() returns
error pointer to dc->writeback_thread, then a memory leak is avoided.
