Fix #148061: Prevent unknown socket type from crashing when reading file

Browse Source 
`socket.socket_typeinfo()` can be nullptr when reading blend files that
contains custom socket types that are not registered yet. This fix
prevents crashing when this happenes (but the socket will stay
unregistered).
