Subject: [PATCH] dmaengine: pl330: fix return status on pending transfers

The pl330_tx_status() function returns the desc->status if the
dma_cookie_status() call does indicate the cookie completed,
however the desc->status is not look directly compatible. Sparse
throws the following warning:

pl330.c:2262:35: warning: mixing different enum types
pl330.c:2262:35:     int enum desc_status  versus
pl330.c:2262:35:     int enum dma_status

Attempt to fix this by adding a switch statement to turn the
desc->status into a dma_status.

Note, this has only been tested with the dmatest suite.
