RDMA/core: Set sgtable nents when using ib_dma_virt_map_sg()
ib_dma_map_sgtable_attrs() should be mapping the sgls and setting nents
but the ib_uses_virt_dma() path falls back to ib_dma_virt_map_sg() which
will not set the nents in the sgtable.
Check the return value (per the map_sg calling convention) and set
sgt->nents appropriately on success.
Fixes: 79fbd3e1241c ("RDMA: Use the sg_table directly and remove the opencoded version from umem")
