wifi: iwlwifi: mvm: don't drop unencrypted MCAST frames

Browse Source 
[ Upstream commit 8e5a26360cbe29b896b6758518280d41c3704d43 ]

MCAST frames are filtered out by the driver if we are not
authorized yet.
Fix it to filter out only protected frames.

Fixes: 147eb05f24 ("iwlwifi: mvm: always tell the firmware to accept MCAST frames in BSS")
