Subject: [PATCH 7/9] generic/620: Remove -b blocksize option for ext4

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.

mkfs.ext4: Input/output error while writing out and closing file system
