iwlwifi: don't advertise TWT support
[ Upstream commit 1db5fcbba2631277b78d7f8aff99c9607d29f6d8 ]
Some APs misbehave when TWT is used and cause our firmware to crash.
We don't know a reasonable way to detect and work around this problem
in the FW yet. To prevent these crashes, disable TWT in the driver by
stopping to advertise TWT support.
