udf: Fix off-by-one error when discarding preallocation

Browse source

[ Upstream commit f54aa97fb7 ]

The condition determining whether the preallocation can be used had
an off-by-one error so we didn't discard preallocation when new
allocation was just following it. This can then confuse code in
inode_getblk().
