sunrpc: handle -ENOTCONN in xs_tcp_setup_socket()

Browse Source 
[ Upstream commit 10f0740234 ]

xs_tcp_finish_connecting() can return -ENOTCONN but the switch statement
in xs_tcp_setup_socket() treats that as an unhandled error.

If we treat it as a known error it would propagate back to
call_connect_status() which does handle that error code.  This appears
to be the intention of the commit (given below) which added -ENOTCONN as
a return status for xs_tcp_finish_connecting().

So add -ENOTCONN to the switch statement as an error to pass through to
the caller.
