dmaengine: altera-msgdma: properly free descriptor in msgdma_free_descriptor

[ Upstream commit 54e4ada1a4206f878e345ae01cf37347d803d1b1 ]

Remove list_del call in msgdma_chan_desc_cleanup, this should be the role
of msgdma_free_descriptor. In consequence replace list_add_tail with
list_move_tail in msgdma_free_descriptor.

This fixes the path:
   msgdma_free_chan_resources -> msgdma_free_descriptors ->
   msgdma_free_desc_list -> msgdma_free_descriptor

which does not correctly free the descriptors as first nodes were not
removed from the list.
