5.4-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit aa388c72113b7458127b709bdd7d3628af26e9b4 ]
sk_err is set when a (connectible) connect() fails. Effectively, this makes an otherwise still healthy SS_UNCONNECTED socket impossible to use for any subsequent connection attempts.
Clear sk_err upon trying to establish a connection.
