[ Upstream commit 781d2a9a2fc7d0be53a072794dc03ef6de770f3d ] We were checking validity of LVID entries only when getting implementation use information from LVID in udf_sb_lvidiu(). However if the LVID is suitably corrupted, it can cause problems also to code such as udf_count_free() which doesn't use udf_sb_lvidiu(). So check validity of LVID already when loading it from the disk and just disable LVID altogether when it is not valid.
