wifi: ath12k: fix wrong handling of CCMP256 and GCMP ciphers
Currently for CCMP256, GCMP128 and GCMP256 ciphers, in
ath12k_install_key() IEEE80211_KEY_FLAG_GENERATE_IV_MGMT is not set and
in ath12k_mac_mgmt_tx_wmi() a length of IEEE80211_CCMP_MIC_LEN is reserved
for all ciphers.
This results in unexpected drop of protected management frames in case
either of above 3 ciphers is used. The reason is, without
IEEE80211_KEY_FLAG_GENERATE_IV_MGMT set, mac80211 will not generate
CCMP/GCMP headers in TX frame for ath12k.
Also MIC length reserved is wrong and such frames are dropped by hardware.
Fix this by setting IEEE80211_KEY_FLAG_GENERATE_IV_MGMT flag for above
ciphers and by reserving proper MIC length for those ciphers.
