    Fix deserializing context with missing profile
    
    k5_internalize_context() tolerates EINVAL and ENOENT failures from
    profile_ser_internalize(), which should allow it to continue if a
    configuration file (such as /etc/krb5.conf) is missing in the
    deserializing process.  However, profile_ser_internalize() only
    updates the caller's buffer pointer if the profile was initialized, so
    k5_internalize_context() attempts to read its trailer from the
    serialized profile data and fails.  Change profile_ser_internalize()
    to update the caller's buffer pointer once it has consumed a whole
    profile serialization, whether or not profile_init() succeeds.
