drm/amd/display: Fix stream->link_enc unassigned during stream removal
[Why]
Found when running igt@kms_atomic.
Userspace attempts to do a TEST_COMMIT when 0 streams which calls
dc_remove_stream_from_ctx. This in turn calls link_enc_unassign which
ends up modifying stream->link = NULL directly, causing the global
link_enc to be removed preventing further link activity and future link
validation from passing.
[How]
We take care of link_enc unassignment at the start of
link_enc_cfg_link_encs_assign so this call is no longer necessary.
Fixes global state from being modified while unlocked.
