    udf: Release preallocation on last writeable close · b07ef352

    Commit 6fb1ca92 "udf: Fix race between write(2) and close(2)"
    changed the condition when preallocation is released. The idea was that
    we don't want to release the preallocation for an inode on close when
    there are other writeable file descriptors for the inode. However the
    condition was written in the opposite way so we released preallocation
    only if there were other writeable file descriptors. Fix the problem by
    changing the condition properly.
