[PATCH][next] dmaengine: xilinx: xdma: remove redundant check on ret

[Colin Ian King]

The variable ret is being checked for an error and returning ret
and the following statement returns ret too. The if check is
redundant, and remove it. Just return the value returned from
the call to regmap_write.
