dmaengine: dmatest: Add check for supported buffer count (sg_buffers) When using dmatest with sg_buffers=128 I stumbled upon the problem, that the "map_cnt" variable of "struct dmaengine_unmap_data" was set to 0. "map_cnt" is an "u8" variable, resulting in an overrun when its value is set to src_cnt + dst_cnt, to twice the sg_buffer value. This patch adds a small check to dmatest, so that this confusing error is detected and the test is aborted.
