iwlwifi: mvm: Allow iwl_mvm_mac_mgd_prepare_tx() when associated
The FW does not allocate quota air time for the binding of a station
MAC before iwlmvm indicates that it is associated. Currently iwlmvm
indicates that the MAC is associated only after hearing a beacon from
the AP. In case a deauthentication frame is sent before the MAC is
associated, the frame might not be sent as the corresponding binding
is not scheduled.
To handle such cases, set IEEE80211_HW_DEAUTH_NEED_MGD_TX_PREP in the
HW flags, requesting mac80211 to call the mgd_prepare_tx() callback
before transmitting a deauthentication frame if associated but no
beacon was heard from the AP.
In addition, do not warn in iwl_mvm_mac_mgd_prepare_tx() when already
associated as now the callback can be called also when associated.
