btrfs: scrub: fix race between scrub and scrub progress ioctl
The scrub progress ioctl is copying the scrub progress stats without
acquiring the spinlock that protects it and a concurrent scrub can be
updating the stats at the same time which can lead to load tearing
issues. So take the spinlock when copying the progress stats.
