drm/probe-helper: Check epoch counter in output_poll_execute()
drm_helper_hpd_irq_event() checks the epoch counter to determine
connector status change. This was introduced in
commit 5186421cbfe2 ("drm: Introduce epoch counter to drm_connector").
Do the same for output_poll_execute() so it can detect other changes
beside connection status value changes.
v2:
- Add Fixes tag (Daniel)
Fixes: 5186421cbfe2 ("drm: Introduce epoch counter to drm_connector")
