wifi: mt76: mt7996: fix MLD ID in MAC TXD and HIF TXP

Problem:
MCU command timeout while the firmware state is normal, and the
firmware keeps showing the error log "ERROR!! NO PAUSE...".

Root cause:
If the MLD_ID field in the TXD is neither the primary link id nor the
secondary link id, it may lead to a firmware busy loop when the third
link is in power saving mode.

Remap frames directed to a third link to the primary link wcid. Since
TX status events and txfree completions carry the wcid the firmware
saw, use the remapped wcid for packet id tracking and non-AQL packet
accounting as well, while the frame keeps its original link context
for addressing, band and OMAC selection.
