net: ethernet: davinci_cpdma: decrease the desc count when cleaning up the remaining packets

[ Upstream commit ffb5ba90017505a19e238e986e6d33f09e4df765 ]

chan->count is used by rx channel. If the desc count is not updated by
the clean up loop in cpdma_chan_stop, the value written to the rxfree
register in cpdma_chan_start will be incorrect.
