RDMA/umem: Use correct value for SG entries in sg_copy_to_buffer()
With page combining, the assumption that number of SG entries in umem SGL
equal to number of system pages in umem no longer holds.
umem->sg_nents tracks the SG entries in umem SGL. Use it in
sg_pcopy_to_buffer() as opposed to ib_umem_num_pages(umem).
Fixes: d10bcf947a3e ("RDMA/umem: Combine contiguous PAGE_SIZE regions in SGEs")
