[ Upstream commit 8b894adb2b7e1d1e64b8954569c761eaf3d51ab5 ]
9p/rdma would sometimes drop the connection and display errors in
recv_done when the user does ^C.
The errors were caused by recv buffers that were posted at the time
of disconnect, and we just do not want to disconnect when
down_interruptible is... interrupted.
