sysfs: fix problems with binary files

commit 4503efd0891c40e30928afb4b23dc3f99c62a6b2 upstream.

Some sysfs binary files don't like having 0 passed to them as a size.
Fix this up at the root by just returning to the vfs if userspace asks
us for a zero sized buffer.

Thanks to Pavel Roskin for pointing this out.
