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.
