scsi: mpt3sas: Fix return value check of dma_get_required_mask()
Fix the incorrect return value check of dma_get_required_mask(). Due to
this incorrect check, the driver was always setting the DMA mask to 63 bit.
Link: https://lore.kernel.org/r/20220913120538.18759-2-sreekanth.reddy@broadcom.com
Fixes: ba27c5cf286d ("scsi: mpt3sas: Don't change the DMA coherent mask after allocations")
