ioatdma: silence GCC warnings
Building dma_v3.o triggers a GCC warning:
drivers/dma/ioat/dma_v3.c: In function ‘__ioat3_prep_pq16_lock’:
drivers/dma/ioat/dma_v3.c:264:11: warning: array subscript is below array bounds [-Warray-bounds]
drivers/dma/ioat/dma_v3.c:264:11: warning: array subscript is below array bounds [-Warray-bounds]
This warning is caused by pq16_set_src(). It uses "int idx" as an index
to an eight element array. Changing "idx" to "unsigned" silences this
warning. Apparently GCC can then determine that "idx" will never be
negative.
