wifi: iwlwifi: mvm: don't support the reset handshake for old firmwares

[ Upstream commit 0eaa1f245a ]

-77.ucode doesn't contain the fixes for this flow it seems.
Don't use the firmware reset handshake even if the firmware claims
support for it.

Fixes: 906d4eb844 ("iwlwifi: support firmware reset handshake")
