[PATCH] tipc: set sk_err correctly when connection fails

[<erik.hugne@ericsson.com>]

From: Erik Hugne <erik.hugne@ericsson.com>

This fixes a problem when connect() fails and returns the error
code as a positive value, whereas errno itself is never set. The
reason is that error codes set in sk_err should never be inverted.
