[PATCH 2/3] thinkpad_acpi: Don't repeat ourselves in hotkey_init_tablet_mode()

[Lyude <lyude@redhat.com>]

There's no need to have multiple copies of the logic we use for checking
whether or not we're in tablet mode, so just use
hotkey_get_tablet_mode() when checking the initial state in
hotkey_init_tablet_mode().
