udf: Unify types in anchor block detection
When detecting last recorded block and from it derived anchor block position, we were mixing unsigned long, u32, and sector_t types. Since udf supports only 32-bit block numbers this is harmless but sometimes makes things awkward. Convert everything to udf_pblk_t and also handle the situation when block device size would not fit into udf_pblk_t. Signed-off-by: Jan Kara <jack@suse.cz>
