Add spinlock driver_lock to protect queue_count, working_queue and request_queue from concurrent access between IOCTL handler and block device request handler. Wrap all cross-context flag reads (stop_signal, data_drive_active, lockup_detected, return_zeros_on_error, io_scsi_only) with READ_ONCE and all writes with WRITE_ONCE to prevent compiler-mangled reads and tearing. These flags are accessed from both the IOCTL control path and the block device data path without an explicit lock. Protect queue counter resets in START command with the spinlock.
