BUG/MEDIUM: mux-spop: Wait end of handshake to declare a spop connection ready

A SPOP connection must not be considered as ready while the hello handshake
is not finished with success. In addition, no error or shutdown must have
been reported for the underlying connection. Otherwise a freshly openned
spop connexion may be reused while it is in fact dead, leading to a
connection retry.

This patch must be backported to 3.1.
