[PATCH 2/9] parallels: Fix data_end field value in parallels_co_check()

[Alexander Ivanov]

When an image is opened for check there is no error if an offset in the BAT
points outside the image. In such a way we can repair the image.
Out-of-image offsets are repaired in the check, but data_end field
still points outside. Fix this field by file size.
