mac80211: don't send deferred frames outside the SP

Frames that are sent between
ampdu_action(IEEE80211_AMPDU_TX_START) and the move to the
HT_AGG_STATE_OPERATIONAL state are buffered.
If we try to start an A-MPDU session while the peer is
sleeping and polling frames with U-APSD, we may have frames
that will be buffered by ieee80211_tx_prep_agg. These frames
have IEEE80211_TX_CTL_NO_PS_BUFFER set since they are sent to
a sleeping client and possibly IEEE80211_TX_STATUS_EOSP.
If the frame is buffered, we need clear these two flags
since they will be re-sent after the move to
HT_AGG_STATE_OPERATIONAL state which is very likely to
happen after the SP ends.
