[PATCH] drm/radeon: avoid bouncing connector status btw disconnected & unknown

[j.glisse at gmail.com]

From: Jerome Glisse <jglisse at redhat.com>

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.
