[PATCH] symlink doesn't support kobj name > 20 charaters (KOBJ_NAME_LEN)

Since symlink.c uses "name" field of a kobj when it calculates the
length,  it gets a wrong value if the kobj's name  has more than 20
charathers.  A correct way to do that is to call kobject_name(kobj)
instead of using kobj->name directly.
