[PATCH] smb: client: hide unused cifs_debug_dirs_proc_ops

[Arnd Bergmann <arnd@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

When CONFIG_CIFS_DEBUG2 is disabled, the only reference to this
function is hidden, causing a harmless warning:

fs/smb/client/cifs_debug.c:395:30: error: 'cifs_debug_dirs_proc_ops' defined but not used [-Werror=unused-const-variable=]
  395 | static const struct proc_ops cifs_debug_dirs_proc_ops = {
      |                              ^~~~~~~~~~~~~~~~~~~~~~~~

Make the #ifdef checks around them consistent by always using
the DEBUG2 variant.

Fixes: 63bff18d4aa0 ("smb: client: fix (remove) drop_dir_cache module parameter")
