wifi: iwlwifi: mvm: revert gen2 TX A-MPDU size to 64
[ Upstream commit 4a7aace2899711592327463c1a29ffee44fcc66e ]
We don't actually support >64 even for HE devices, so revert
back to 64. This fixes an issue where the session is refused
because the queue is configured differently from the actual
session later.
