scsi: sg: clean up gfp_mask in sg_build_indirect
commit a45b599ad808c ("scsi: sg: allocate with __GFP_ZERO in
sg_build_indirect()") changed the call to alloc_pages to always use
__GFP_ZERO. Just above that, though, there was this:
if (!capable(CAP_SYS_ADMIN) || !capable(CAP_SYS_RAWIO))
gfp_mask |= __GFP_ZERO;
And there's only one user of the gfp_mask. Just or in the __GFP_ZERO
flag at the top of the function and be done with it.
