[Devel] [PATCH RH8] ve: Change error code in vz_security_protocol_check to -EPROTONOSUPPORT

[Valeriy Vdovin]

'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.
