Subject: [PATCH 2/3] f2fs: zone: allow IPU for regular file in regular block device
blkzoned feature enables lfs mode by default, for data updates from
regular file, it only allow to use OPU, this patch changes to allow
to use IPU if regular file's data block locates in regular block
device, if data block locates in zoned block device, it still uses
OPU.
