svcrdma: Add svc_rdma_get_context() API that is allowed to fail

[ Proposed for v4.4 ]

To support backward direction calls, I'm going to add an
svc_rdma_get_context() call in the client RDMA transport.

Called from ->buf_alloc(), we can't sleep waiting for memory.
So add an API that can get a server op_ctxt but won't sleep.
