scsi: 3w-sas: fix calls to dma_set_mask_and_coherent()

Browse Source 
commit 1feb3b0229 upstream.

The change to use dma_set_mask_and_coherent() incorrectly made a second
call with the 32 bit DMA mask value when the call with the 64 bit DMA mask
value succeeded.

Fixes: b1fa122930 ("scsi: 3w-sas: fully convert to the generic DMA API")
