tcp_splice: Simplify clean up logic

Currently tcp_splice_flow_defer() contains specific logic to determine
if we're far enough initialised that we need to close pipes and/or
sockets.  This is potentially fragile if we change something about the
order in which we do things.  We can simplify this by initialising the
pipe and socket fields to -1 very early, then close()ing them if and
only if they're non-negative.

This lets us remove a special case cleanup if our connect() fails.
This will already trigger a CLOSING event, and the socket fd in
question is populated in the connection structure.  Thus we can let
the new cleanup logic handle it rather than requiring an explicit
close().
