From: Namjae Jeon <namjae.jeon@samsung.com>

We execute collapse range multiple times on same file.
Each collapse range call collapses a single alternate block.
After the test execution, file will be left with 80 blocks and
as much number of extents.
We also check for file system consistency after the completion.
