flashrom_tester: Call crossystem with write protect argument
crossystem uses flashrom to gather data on some platforms. To avoid
firmware lock deadlock, call crossystem before initialising libflashrom.
When querying hardware write protect status, provide an argument to
crossystem so that only that field is queried. This also avoids the
deadlock, and improves performance.
