[PATCH -next] dmaengine: xilinx: xdma: Fix some kernel-doc comments

[Yang Li]

Make the description of @xdma_chan to @xchan to silence the warnings:

drivers/dma/xilinx/xdma.c:283: warning: Function parameter or member 'xchan' not described in 'xdma_xfer_start'
drivers/dma/xilinx/xdma.c:283: warning: Excess function parameter 'xdma_chan' description in 'xdma_xfer_start'
