    drm/i915/dp_mst: Fix encoder HW state readout for UHBR MST
    
    The encoder HW/SW state verification should use a SW state which stays
    unchanged while the encoder/output is active. The intel_dp::is_mst flag
    used during state computation to choose between the DP SST/MST modes can
    change while the output is active, if the sink gets disconnected or the
    MST topology is removed for another reason. A subsequent state
    verification using intel_dp::is_mst leads then to a mismatch if the
    output is disabled/re-enabled without recomputing its state.
    
    Use the encoder's active MST link count instead, which will be always
    non-zero for an active MST output and will be zero for SST.
