[PATCH 3/6] drm/rockchip: Fix vop2_create_crtcs() error path cleanup in vop2_bind()

[Jiaqi]

In vop2_bind(), when vop2_create_crtcs() fails, the function returns
immediately without calling vop2_destroy_crtcs(). This means any
of_node references stored in vp->crtc.port by vop2_create_crtcs() are
leaked, as they are only released in vop2_destroy_crtcs().

Additionally, if the component framework retries the bind (e.g., due to
-EPROBE_DEFER from downstream components), the previously registered
IRQ via devm_request_irq() will cause subsequent attempts to return
-EBUSY, permanently breaking the driver.

Fix by ensuring vop2_create_crtcs() failures go through the err_crtcs
label, which calls vop2_destroy_crtcs() to properly release all
resources including of_node references.
