Minor error in setting error

[Jason Curl <jason@xxxxxxxxxxxxxxxxxxxxxxxx>]

Hi,

I've found what appears to be a bug in code. the function ssh_set_error 
takes an int for an input, but there appears to be an enum for this 
called ssh_error_types_e. In almost all cases usage of ssh_set_error 
uses a value from the enum, except in messages.c line 864 which has one 
line of code:

             ssh_set_error(session, SSH_LOG_PACKET, "USERAUTH_REQUEST: 
gssapi-with-mic missing OID");

In this case, SSH_LOG_PACKET=3 which is the same value as SSH_EINTR=3.

Regards,
Jason.
