udf: Fortify LVID loading
A user has reported an oops in udf_statfs() that was caused by numOfPartitions entry in LVID structure being corrupted. Fix the problem by verifying whether numOfPartitions makes sense at least to the extent that LVID fits into a single block as it should. Reported-by: Juergen Weigert <jw@suse.com> Signed-off-by: Jan Kara <jack@suse.cz>
