[1/2] btrfs-progs: print out the correct minimum size for zoned file systems

While trying to get the ZNS testing running I ran into a problem with
making a small file system for one of the tests, but the error output
didn't make sense because it said the minimum size was 114294784 bytes,
and I was trying to make a file system of size 419430400 bytes.  The
problem here is that we were spitting out min_dev_size, which isn't the
minimum size for the ZNS configuration.  Fix the output to match the
actual size limit.
