drm/radeon: avoid bouncing connector status btw disconnected & unknown
commit 340764465aa4a586ca332e61ae64883e5ad6f183 upstream.
Since force handling rework of d0d0a225e6ad43314c9aa7ea081f76adc5098ad4
we could end up bouncing connector status btw disconnected and unknown.
When connector status change a call to output_poll_changed happen which
in turn ask again for detect but with force set.
So set the load detect flags whenever we report the connector as
connected or unknown this avoid bouncing btw disconnected and unknown.
