This patch is incorrect, you've introduced a double unlock.

The driver may sleep under a spin lock, and the function call path is:
journal_wait_for_write (acquire the lock by spin_lock)
closure_sync
schedule --> may sleep
To fix it, the lock is released before "closure_sync", and the lock is
acquired again after this function.
