mt76_tx() queues frames on wcid->tx_pending for async processing by tx_worker. In __mt76_set_channel(), the worker gets disabled before it may have run, and the subsequent wait only checks DMA ring queues, not the software pending list. This means frames like nullfunc PS frames from mt76_offchannel_notify() may never be transmitted on the correct channel. Fix this by running mt76_txq_schedule_pending() synchronously after disabling the tx_worker but before setting MT76_RESET, which would otherwise cause mt76_txq_schedule_pending_wcid() to bail out.
