Add this test to check for regression which was reported when ext4 bmap
aops was moved to use iomap APIs. jbd2 calls bmap() kernel function
from fs/inode.c which was failing since iomap_bmap() implementation earlier
returned 0 for block addr > INT_MAX.
This regression was fixed with following kernel commit [1]
commit b75dfde1212991b24b220c3995101c60a7b8ae74
("fibmap: Warn and return an error in case of block > INT_MAX")
[1]: https://patchwork.ozlabs.org/patch/1279914
w/o the kernel fix we get below errors and mount fails
