Daniel Vetter ea497bb920 drm: rework delayed connector cleanup in connector_iter 
PROBE_DEFER also uses system_wq to reprobe drivers, which means when
that again fails, and we try to flush the overall system_wq (to get
all the delayed connectore cleanup work_struct completed), we
deadlock.

Fix this by using just a single cleanup work, so that we can only
flush that one and don't block on anything else. That means a free
list plus locking, a standard pattern.

v2:
- Correctly free connectors only on last ref. Oops (Chris).
- use llist_head/node (Chris).

v3
- Add init_llist_head (Chris).

Fixes: a703c55004 ("drm: safely free connectors from connector_iter")
Fixes: 613051dac4 ("drm: locking&new iterators for connector_list")
