ioat3: fix uninitialized var warnings

drivers/dma/ioat/dma_v3.c:489: warning: 'xor' may be used uninitialized in this function
drivers/dma/ioat/dma_v3.c:486: warning: 'desc' may be used uninitialized in this function
drivers/dma/ioat/dma_v3.c: In function '__ioat3_prep_pq_lock':
drivers/dma/ioat/dma_v3.c:631: warning: 'pq' may be used uninitialized in this function
drivers/dma/ioat/dma_v3.c:628: warning: 'desc' may be used uninitialized in this function
gcc-4.0, unlike gcc-4.3, does not see that these variables are
initialized before use. Convert the descriptor loops to do-while make
this initialization apparent.
