ext4 with 64k blocksize fails with below error for this given test which
requires dmhugedisk. Also since dax is not supported for this test, so
make sure to remove -b option, if set by config file for ext4 FSTYP for
the test to then use 4K blocksize by default.

Looking at this test, I'm not convinced it actually does the right
thing when the block size is 64k, since the whole point is to test
what happens when the block number > INT_MAX.  So we should be able to
fix the block size to be 1k, which would allow us to use a smaller
dmhugedisk, and then skip this test if dax is enabled.

OTOH, generic/620 runs pretty quicky, so perhaps it's better to do
thie quick fix: hardcode the block size to 4k, and then skip it if dax
&& page_size != 4k.

Ok, so it is time to implement _mkfs_dev_blocksized() something like how we have
for _scratch_mkfs_blocksized(). This is since we can have different way of
passing blocksize parameter for mkfs prog for different filesystems.
