xfstests: more 214 updates

A few more updates for the 214 fallocate test, since
ext4 is having some fallocate trouble these days.

First off, updated 214.out was missing from the previous
commit to this file.

Second, run each test against a new filename and don't
remove it, so that the post-test fs check will have
more work to do.

Third, and a newly-found corruption case for ext4.
