net/mlx5e: Bring back bfreg uar map dedicated pointer
4K Uar series modified the mlx5e driver to use the new bfreg API, and mistakenly removed the sq->uar_map iomem data path dedicated pointer, which was meant to be read from xmit path for cache locality utilization. Fix that by returning that pointer to the SQ struct.

each finish_fault(). Check and free it at the outer level in do_fault(), then we don't need to worry in alloc_set_pte(), and can restore that to how it was (I cannot find any reason to pte_free() under lock as it was doing). And fix a separate pagetable leak, or crash, introduced by the same change, that could only show up on some ppc64: why does do_set_pmd()'s failure case attempt to withdraw a pagetable when it never deposited one, at the same time overwriting (so leaking) the vmf->prealloc_pte? Residue of an earlier implementation, perhaps? Delete it. Fixes: 953c66c2b22a ("mm: THP page cache support for ppc64") Cc: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Cc: Kirill A.
