scsi: mpt3sas: fix dma_addr_t casts
The newly added base_make_prp_nvme function triggers a build warning on
some 32-bit configurations:
drivers/scsi/mpt3sas/mpt3sas_base.c: In function 'base_make_prp_nvme':
drivers/scsi/mpt3sas/mpt3sas_base.c:1664:13: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
msg_phys = (dma_addr_t)mpt3sas_base_get_pcie_sgl_dma(ioc, smid);
After taking a closer look, I found that the problem is that the new
code mixes up pointers and dma_addr_t values unnecessarily.
This changes it to use the correct types consistently, which lets us get
rid of a lot of type casts in the process. I'm also renaming some
variables to avoid confusion between physical and dma address spaces
that are often distinct.
