Subject: udf: fix udf_add_free_space
From: Marcin Slusarz <marcin.slusarz@xxxxxxxxx>
In commit 742ba02a51c8d0bf5446b154531179760c1ed0a2 (udf: create common
function for changing free space counter) by accident I reversed safety
condition which lead to null pointer dereference in case of media error and
wrong counting of free space in normal situation
