f2fs: support fs shutdown
This patch introduces a generic ioctl for fs shutdown, which was used by xfs.
If this shutdown is triggered, filesystem stops any further IOs according to the
following options.
1. FS_GOING_DOWN_FULLSYNC
: this will flush all the data and dentry blocks, and do checkpoint before
shutdown.
2. FS_GOING_DOWN_METASYNC
: this will do checkpoint before shutdown.
3. FS_GOING_DOWN_NOSYNC
: this will trigger shutdown as is.
