All usable bits in enum mac80211_tx_control_flags are depleted. In
order to allow aditional control flag assigments, we introduce a
new u16 variable ieee8011_tx_info->control.flags2 with its
corresponding enum mac80211_tx_control_flags2. Such tx control flags
within ieee80211_tx_info->flags that are only used in the tx path
while ieee80211_tx_info->control is valid can be moved to
ieee80211_tx_control->control.flags2.
