    display-config: fix the max potential number of logical monitors
    
    The max potential number of logical monitors (i.e. MetaMonitorInfos)
    is the number of CRTCs, not the number of outputs.
    
    In cases where we have more enabled CRTCs than connected outputs we
    would end up appending more MetaMonitorInfos to the GArray than the
    size it was initialized with which means the array would get
    re-allocated rendering invalid some MetaCRTC->logical_monitor pointers
    assigned previously and thus ending in crashes later on.
