scsi: mpt3sas: Fix return value check of dma_get_required_mask()

Browse Source 
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.

Fixes: ba27c5cf28 ("scsi: mpt3sas: Don't change the DMA coherent mask after allocations")
