xfs: always complete the buffer inline in xfs_buf_submit

Browse Source 
xfs_buf_submit now only completes a buffer on error, or for in-memory
buftargs.  There is no point in using a workqueue for the latter as
the completion will just wake up the caller.  Optimize this case by
avoiding the workqueue roundtrip.
