f2fs: Check zoned block feature for host-managed zoned block devices
The F2FS_FEATURE_BLKZONED feature indicates that the drive was formatted with zone alignment optimization. This is optional for host-aware devices, but mandatory for host-managed zoned block devices. So check that the feature is set in this latter case. Signed-off-by: Damien Le Moal <damien.lemoal@wdc.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
