udf: Fix crash on IO error during truncate

commit d3ca4651d05c0ff7259d087d8c949bcf3e14fb46 upstream.

When truncate(2) hits IO error when reading indirect extent block the
code just bugs with:

kernel BUG at linux-4.15.0/fs/udf/truncate.c:249!
...

Fix the problem by bailing out cleanly in case of IO error.
