udf: Release preallocation on last writeable close
Commit 6fb1ca92a640 "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.
