drm/amd/display: Clear HDMI HPD pending work only if it is enabled
[Why&How]
On amdgpu_dm_connector_destroy(), the driver attempts to cancel pending
HDMI HPD work without checking if the HDMI HPD is enabled.
Added a check that it is enabled before clearing it.
Fixes: 6a681cd90345 ("drm/amd/display: Add an hdmi_hpd_debounce_delay_ms module")
