btrfs: use READ/WRITE_ONCE for fs_devices->read_policy
Since we can read/modify the value from the sysfs interface concurrently,
it would be better to protect it from compiler optimizations.
Currently, there is only one read policy BTRFS_READ_POLICY_PID available,
so no actual problem can happen now. This is a preparation for the future
expansion.
