[patch] configfs: use capped length for ->store_attribute()

From: Dan Carpenter
Date: Tue Apr 30 2013 - 03:28:51 EST

The difference between "count" and "len" is that "len" is capped at
4095. Changing it like this makes it match how sysfs_write_file() is

This is a static analysis patch. I haven't found any store_attribute()
functions where this change makes a difference.
