drivers/net/wan/hdlc_cisco: Add hard_header_len

This driver didn't set hard_header_len. This patch sets hard_header_len for it according to its header_ops->create function. This driver's header_ops->create function (cisco_hard_header) creates a header of (struct hdlc_header), so hard_header_len should be set to sizeof(struct hdlc_header).
