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

This reverts commit e0e0747d.

As noted in 1a2dcbdd ("scsi: mpt3sas: re-do lost mpt3sas DMA mask
fix") in mainline there was a mis-merge in commit 62e6e594 ("Merge
tag 'scsi-misc' of
git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi"). causing that
the fix needed to be redone later on again. To make series of patches
apply cleanly to the stable series where e0e0747d ("scsi: mpt3sas:
Fix return value check of dma_get_required_mask()") was backported,
revert the aforementioned commit.

No upstream commit exists for this commit.
