IB/rdmavt: Validate remote_addr during loopback atomic tests  

The rdma-core test suite sends an unaligned remote address and expects a  
failure.  

ERROR: test_atomic_non_aligned_addr (tests.test_atomic.AtomicTest)  

The qib/hfi1 rc handling validates properly, but the test has the client  
and server on the same system.  

The loopback of these operations is a distinct code path.  

Fix by syntaxing the proposed remote address in the loopback code path.  

Fixes: 15703461533a ("IB/{hfi1, qib, rdmavt}: Move ruc_loopback to rdmavt")
