Commit 5675add36e ("RPC/RDMA: harden connection logic against
missing/late rdma_cm upcalls.") replaced wait_for_completion() calls
with these two call sites.
The original wait_for_completion() calls were added in the initial
commit of verbs.c, which was commit c56c65fb67 ("RPCRDMA: rpc rdma
verbs interface implementation"), but these returned void.
rpcrdma_create_id() is called by the RDMA connect worker, which
probably won't ever be interrupted. It is also called by
rpcrdma_ia_open which is in the synchronous mount path, and ^C is
possible there.
Add a bit of logic at those two call sites to return if the waits
return ERESTARTSYS.
