When migration capability @rdma-pin-all is true, but the server cannot
honor it, qemu_rdma_connect() calls macro ERROR(), then returns
success.
ERROR() sets an error. Since qemu_rdma_connect() returns success, its
caller rdma_start_outgoing_migration() duly assumes @errp is still
clear. The Error object leaks.
ERROR() additionally reports the situation to the user as an error:
RDMA ERROR: Server cannot support pinning all memory. Will register memory dynamically.
Is this an error or not? It actually isn't; we disable @rdma-pin-all
and carry on. "Correcting" the user's configuration decisions that
way feels problematic, but that's a topic for another day.
Replace ERROR() by warn_report(). This plugs the memory leak, and
emits a clearer message to the user.
