[Libguestfs] [PATCH] ext: change e2fsck retcode processing during resize

[Maxim Perevedentsev]

e2fsck returns 1 in case of "file system errors corrected".
We treat it as success in normal e2fsck, but fail if e2fsck
is run by resize2fs.

Change 'manual' execution of e2fsck to dedicated function call.
