msgdma_chan_desc_cleanup iterates the done list for each completed
descriptor while we need to do it once after all descriptors are
completed.
This fixes a Sparse warning because we first take the lock in
msgdma_tasklet.
- Move locking to msgdma_chan_desc_cleanup.
- Move call to msgdma_chan_desc_cleanup outside of the critical section of
msgdma_tasklet.

completing all descriptors")
