dmaengine: mv_xor_v2: remove unnecessary write to DESQ_STOP register 



Remove unnecessary write to DESQ_STOP register, this register is used to
enable or disable the XOR engine, and not to issue all pending
descriptors in the queue. mv_xor_v2 driver already writes to this
register and enable XOR engine in the mv_xor_v2_descq_init() function,
called during initialization.
