pf: qid and pqid can be uint16_t
tag2name() returns a uint16_t, so we don't need to use uint32_t for the qid (or pqid). This reduces the size of struct pf_kstate slightly. That in turn buys us space to add extra fields for dummynet later. Happily these fields are not exposed to user space (there are user space versions of them, but they can just stay uint32_t), so there's no ABI breakage in modifying this.
