Qu Wenruo d60a374907 btrfs: async-thread: Fix a use-after-free error for trace 
commit 0a95b851370b84a4b9d92ee6d1fa0926901d0454 upstream.

Parameter of trace_btrfs_work_queued() can be freed in its workqueue.
So no one use use that pointer after queue_work().

Fix the user-after-free bug by move the trace line before queue_work().
