[PATCH] cw1200: remove an unneeded NULL check on list iterator

[Xiaomeng Tong <xiam0nd.tong@gmail.com>]

The list iterator 'item' is always non-NULL so it doesn't need to be
checked. Thus just remove the unnecessary NULL check. Also remove the
unnecessary initializer because the list iterator is always initialized.
