drm: prevent double-(un)registration for connectors
[ Upstream commit e73ab00e9a0f1731f34d0620a9c55f5c30c4ad4e ]
If we're unlucky then the registration from a hotplugged connector
might race with the final registration step on driver load. And since
MST topology discover is asynchronous that's even somewhat likely.
v2: Also update the kerneldoc for @registered!
v3: Review from Chris:
- Improve kerneldoc for late_register/early_unregister callbacks.
- Use mutex_destroy.
