commit 4028bccb 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: 15703461 ("IB/{hfi1, qib, rdmavt}: Move ruc_loopback to rdmavt")
