_require_ext4_bigalloc and _require_ext4_mkfs_bigalloc create a
200k fs. DAX (as XIP before it) relies on a fs block size ==
system page size; ie 4k for us. With a 200k fs size limit,
mkfs refuses to create a filesystem with a 4k block size, so
the check fails, but for a bogus reason.
Increasing the fs size to 512m allows mkfs to create a filesystem
with 4k block size, so the test passes.
