net: ethernet: ti: davinci_cpdma: free memory while channel destroy

Browse Source 
While create/destroy channel operation memory is not freed. It was
supposed that memory is freed while driver remove. But a channel
can be created and destroyed many times while changing number of
channels with ethtool.

Based on net-next/master
