Mikulas Patocka b101e74f9a dm integrity: set journal entry unused when shrinking device ...

commit cc09e8a9dec4f0e8299e80a7a2a8e6f54164a10b upstream.

Commit f6f72f32c2 ("dm integrity: don't replay journal data past the
end of the device") skips journal replay if the target sector points
beyond the end of the device. Unfortunatelly, it doesn't set the
journal entry unused, which resulted in this BUG being triggered:
BUG_ON(!journal_entry_is_unused(je))

Fix this by calling journal_entry_set_unused() for this case.
