[PATCH 1/1] fs: remove the unused mempages parameter

[Denis Cheng <crquan@gmail.com>]

Since the mempages parameter is actually not used, they should be removed.

If applied, now there is only files_init use the mempages parameter,
 	files_init(mempages);
but i don't think the adaptation to mempages in files_init is really useful;
and if files_init also changed to the prototype void (*func)(void),
the wrapper vfs_caches_init would also not need the mempages parameter.
