    sna: Check OPTION_PREFERRED_MODE rather than M_T_USERPREF
    
    During the intial KMS probe, we do not yet have the list of output
    modes, and in particular do not have the list of user preferred modes.
    So, in order to honour the user preferrence, we need to query for any
    preferred mode on the output from the option list.
