    ve: Change error code in vz_security_protocol_check to -EPROTONOSUPPORT
    
    'vz_security_protocol_check' is a part of socket creation routine.
    Socket creation can be split into separate stages:
     - family validation and family specific object creation
     - protocol validation and protocol specific object creation
    First family argument is validated. If family is ok, then the code
    can proceeds to further work with protocol agrument.
    
    As part of family validation procedure for containers
    vz_security_family_check is called. If family is not supported in
    container environment and the current context is container the
    function returns with -EAFNOSUPPORT code.
    
    As part of protocol validation procedure for containers
    vz_security_protocol_check is called. If protocol is not supported
    in container environment and the current context is container the
    function CURRENTLY returns with -EAFNOSUPPORT code, although by
    context of the current socket preparation step it should instead
    return -EPROTONOSUPPORT.
