[PATCH -next] drm/hisilicon/hibmc: Fix wrong pointer passed to PTR_ERR()

[Wei Yongjun]

From: Wei Yongjun <weiyongjun1 at huawei.com>

PTR_ERR should access the value just tested by IS_ERR, otherwise
the wrong error code will be returned.

Fixes: d1667b86795a ("drm/hisilicon/hibmc: Add support for frame buffer")
