commit 4028bccb003cf67e46632dee7f97ddc5d7b6e685 upstream.
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")
