glusterd: Should not cleanup peerinfo too soon.
friend_remove_cbk cleans up peerinfo and the unrefs the associated rpc_clnt
obj. When the cbk is run inside call_bail or saved_frames_unwind, we might end
up destroying the rpc_clnt and associated saved_frames_pool while we are still
using saved_frames to iterate through the frames.
