Lior Amsalem fbd2f7f70b dmaengine: mv_xor: bug fix for racing condition in descriptors cleanup 
commit 9136291f1dbc1d4d1cacd2840fb35f4f3ce16c46 upstream.

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")
