    LinuxKPI: 802.11: adjust timing of sync_from_ni in lkpi_sta_assoc_to_run()
    
    We used to call the (*sta_state) downcall into the driver to set the
    sta state to ASSOC.  After that we did a lot of sync operations incl.
    the lkpi_sta_sync_from_ni() which does a lot of rate and bandwith
    adjustments.   This sync call needs to happen before we set the sta
    to assoc as drivers rely on some of this information, e.g., ht_cap and
    vht_cap (and equivalents for later standards) at that point.  Moving
    this will make, e.g., mt7921 transmit at higher rates than just
    basic_rates.
