RollbackKernelLock previously checked a global to determine recovery mode state. Since we have two copies of vboot_reference in firmware (in coreboot and depthcharge), this creates a problem with synchronization. Remove the global entirely and instead pass the recovery state to RollbackKernelLock. BUG=chrome-os-partner:20913. TEST=Manual. Boot factory install shim in recovery mode and verify TPM clear operations succeed. Boot in dev mode and verify "Lock physical presence" print on UART. BRANCH=FalcoPeppy.
