scsi: mpt3sas: re-do lost mpt3sas DMA mask fix

This is a re-do of commit e0e0747de0ea ("scsi: mpt3sas: Fix return value
check of dma_get_required_mask()"), which I ended up undoing in a
mis-merge in commit 62e6e5940c0c ("Merge tag 'scsi-misc' of
git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi").

The original commit message was

  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.
