According to ECMA 167 rev. 3 (see 3/8.4.2.1), Anchor Volume Descriptor Pointer should be recorded at two or more anchor points located at sectors 256, N, N - 256, where N - is a largest logical sector number at volume space. So we should always try to detect N on UDF volume before trying to find Anchor Volume Descriptor (i.e. calling to udf_find_anchor()). That said, all this patch does is updates the s_last_block even if the udf_vrs() returns positive value. Originally written and tested by Yuri Per, ported on latest mainline by me.
