habanalabs/gaudi: always use single-msi mode The device can get into deadlock in case it use indirect mode for MSI interrupts (multi-msi) and have hard-reset during interrupt storm. To prevent that, always use direct mode which means single-msi mode. The F/W will prevent the host from writing to the indirect MSI registers to prevent any malicious user from causing this scenario.
