[U-Boot] [PATCH v2 3/7] test: fs: run fsck after on fs image after the tests are run

[Jean-Jacques Hiblot]

This is to check the integrity of the FS after the test operations.
This is useful to make sure that the operations are implemented properly,
and are not going to create silent corruptions.
Currently only the integrity of EXT4 filesystems is checked.

Changes in v2:
- Add a FS integrity check at the end of the FS tests
