RDMA/umem: Split ib_umem_get_va() into a thin wrapper around __ib_umem_get_va()
The follow-up patch is going to introduce ib_umem_get_desc(),
the canonical desc-to-umem helper, which needs to pin a userspace VA
without going through the exported ib_umem_get_va() helper so later on
ib_umem_get_va() would use the ib_umem_get_desc() flow too.
Move the existing ib_umem_get_va() to a static __ib_umem_get_va()
and have ib_umem_get_va() as a thin wrapper that calls it.
