mac80211: Fix Ptk0 rekey documentation

@IEEE80211_KEY_FLAG_GENERATE_IV setting is irrelevant for RX.
Move the requirement to the correct section in the PTK0 rekey
documentation.

* Mac80211 drivers should set the @NL80211_EXT_FEATURE_CAN_REPLACE_PTK0 flag
* when they are able to replace in-use PTK keys according to the following
* requirements:
* 1) They do not hand over frames decrypted with the old key to
mac80211 once the call to set_key() with command %DISABLE_KEY has been
completed when also setting @IEEE80211_KEY_FLAG_GENERATE_IV for any key,
* 1) They do not hand over frames decrypted with the old key to mac80211
once the call to set_key() with command %DISABLE_KEY has been completed,
2) either drop or continue to use the old key for any outgoing frames queued
at the time of the key deletion (including re-transmits),
3) never send out a frame queued prior to the set_key() %SET_KEY command
encrypted with the new key and
encrypted with the new key when also needing
@IEEE80211_KEY_FLAG_GENERATE_IV and
4) never send out a frame unencrypted when it should be encrypted.
Mac80211 will not queue any new frames for a deleted key to the driver.
