drm: Fix locking cargo-cult in encoder/plane init/cleanup
Encoders&planes can't be hotplugged, we dont need locking for this
since it's all single-threaded driver setup/teardown code. CRTCs
already don't grab locks.
While at it I noticed that plane's are missing the
drm_modeset_lock_fini() call, so add it.
