[PATCH 3/6 v2] drm/rockchip: Fix vop2_create_crtcs() error path cleanup in vop2_bind()

[Jiaqi <shijiaqi_develop@163.com>]

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().

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.

Note: the IRQ registered via devm_request_irq() earlier in vop2_bind()
is managed by devres and must NOT be manually freed in the error path.
Devres will automatically release it when the device is unbound or
released by the component framework.
