[18/35] SUNRPC: Ensure the RPC client only quits on fatal signals

[Greg KH]

2.6.32-longterm review patch.  If anyone has any objections, please let us know.

------------------

From: Trond Myklebust <Trond.Myklebust@xxxxxxxxxx>

commit 5afa9133cfe67f1bfead6049a9640c9262a7101c upstream.

Fix a couple of instances where we were exiting the RPC client on
arbitrary signals. We should only do so on fatal signals.
