Lior Amsalem b0c1201f22 dmaengine: mv_xor: bug fix for racing condition in descriptors cleanup 
[ Upstream commit 9136291f1d ]

This patch fixes a bug in the XOR driver where the cleanup function can be
called and free descriptors that never been processed by the engine (which
result in data errors).

The cleanup function will free descriptors based on the ownership bit in
the descriptors.

Fixes: ff7b04796d ("dmaengine: DMA engine driver for Marvell XOR engine")
