mac80211: ath11k: fix broadcast failures during GTK rekeying
Revert key_cipher change to NONE when clearing key. Setting to NONE triggers asserts in the firmware and causes broadcast drops with ath11k firmware 2.9.0.1, so until a future blob fixes this, revert this as a workaround.

+Subject: [PATCH] ath11k: Revert: clear the keys properly when DISABLE_KEY
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Reverting the Upstream clear key change added as a part of
+436a4e886598 ("ath11k: clear the keys properly
+when DISABLE_KEY")
+This change exposed a race in WLAN Firmware where target asserts
+are seen frequently due FW not synchronizing ath11k host’s clear
+key commands(CIPHER changes to NONE) with frames in TX queue.
+Hence reverting this change untill FW fixes to synchronize
+ath11k host’s clear key command are available.
