osc/rdma: Add OFI as a full connectivity BTL

Add ofi to the list of btls that do not need to verify connectivity,
since the most common use case of OFI does provide this property.

Rename the list of btls with full connectivity from
ompi_osc_rdma_btls to ompi_osc_rdma_full_connectivity_btls to make
it a little more clear what the list represents.
