[f2fs-dev] [f2fs-tools][PATCH] libf2fs: Throw an error when zone dev info not found

[Surbhi Palande <f2fsnewbie@gmail.com>]

From: Surbhi Palande <csurbhi@gmail.com>

When the -m option is specified to format a Zoned device,
do not fall back to the non-zoned mode in case information
about the device is not found.

Explicitly specify this error to the user.
