scsi: mpt3sas: re-do lost mpt3sas DMA mask fix
This is a re-do of commit e0e0747d ("scsi: mpt3sas: Fix return value check of dma_get_required_mask()"), which I ended up undoing in a mis-merge in commit 62e6e594 ("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.

Petersen <martin.petersen@oracle.com> and this fix was lost when I mis-merged the conflict with commit 9df65096 ("scsi: mpt3sas: Don't change DMA mask while reallocating pools").
