[PATCH V2 1/2] debugfs: fix declaration of debugfs_rename

[Ming Lei <ming.lei@xxxxxxxxxx>]

debugfs_rename() declaration isn't same between CONFIG_DEBUG_FS
and !CONFIG_DEBUG_FS, which causes the following warning in case
of !CONFIG_DEBUG_FS:

   include/linux/debugfs.h:252:47: note: expected 'char *' but argument is of type 'const char *'
     252 |                 struct dentry *new_dir, char *new_name)
         |                                         ~~~~~~^~~~~~~~

So fix declaration of debugfs_rename().
