ath11k: clear the keys properly via DISABLE_KEY

Browse source 
DISABLE_KEY sets the key_len to 0, firmware will not delete the keys if
key_len is 0. Changing from security mode to open mode will cause mcast
to be still encrypted without vdev restart.

Set the proper key_len for DISABLE_KEY cmd to clear the keys in
firmware.

Tested-on: IPQ6018 hw1.0 AHB WLAN.HK.2.5.0.1-01100-QCAHKSWPL_SILICONZ-1

Fixes: d5c65159f2 ("ath11k: driver for Qualcomm IEEE 802.11ax devices")
