drm/nouveau/disp: fix use-after-free in error handling of nouveau_connector_create
commit 1b254b791d7b7dea6e8adc887fbbd51746d8bb27 upstream.
We can't simply free the connector after calling drm_connector_init on it.
We need to clean up the drm side first.
It might not fix all regressions from commit 2b5d1c29f6c4
("drm/nouveau/disp: PIOR DP uses GPIO for HPD, not PMGR AUX interrupts"),
but at least it fixes a memory corruption in error handling related to
that commit.
