drm/bridge: adv7511: Fix incorrect merge conflict resolutions in adv7511_probe()

When merging b140d9d4 ("drm/bridge: adv7511: fix crash on irq during
probe") into nxp branches, it conflicts with the SDK commit ad93dd09
("Revert "drm/bridge: adv7511: Register and attach our DSI device at
probe""). The current merge resolutions introduced two issues:
- Part of codes deleted by SDK commit was restored mistakenly.
- Reference of the label deleted by SDK commit.

Resolve them to fix the build errors.
