wcn36xx: Fix TX data path
This patch contains the following fixes:
- Use correct queue for submitting QoS packet. The queue id to use
is a one-to-one mapping with the TID.
- Don't encrypt a frame with IEEE80211_TX_INTFL_DONT_ENCRYPT flag.
- Use the 'special queue' for null packets, preventing the firmware
to submit it as AMPDU.
