[PATCH 2.6.19-git] Fix error handling in create_files()

[Luca Tettamanti <kronos.it@gmail.com>]

Hello,
current code in create_files() detects an error iff the last
sysfs_add_file fails:

for (attr = grp->attrs; *attr && !error; attr++) {
        error = sysfs_add_file(dir, *attr, SYSFS_KOBJ_ATTR);
}
if (error)
        remove_files(dir,grp);

In order to do the proper cleanup upon failure 'error' must be checked on
every iteration.
