[PATCH] drm/debugfs: Fix dentry reference count leak in drm_debugfs_remove_files

[Miaoqian Lin]

The function uses debugfs_lookup to find dentries,
but did not call dput() after use, causing a reference count leak.
Add dput(dent) after debugfs_remove to properly release the reference.

Fixes: 8e455145d8f1 ("drm/debugfs: rework drm_debugfs_create_files 
implementation v2")
