udf: kill udf_set_blocksize

This helper has been quite useless since sb_min_blocksize was introduced
and is misnamed while we're at it.  Just opencode the few lines in the
caller instead.

- * udf_set_blocksize
- *
- * PURPOSE
- *     Set the block size to be used in all transfers.
- *
- * DESCRIPTION
- *     To allow room for a DMA transfer, it is best to guess big when unsure.
- *     This routine picks 2048 bytes as the blocksize when guessing. This
- *     should be adequate until devices with larger block sizes become common.
- *
- *     Note that the Linux kernel can currently only deal with blocksizes of
- *     512, 1024, 2048, 4096, and 8192 bytes.
- *
- * PRE-CONDITIONS
- *     sb                      Pointer to _locked_ superblock.
- *
- * POST-CONDITIONS
- *     sb->s_blocksize         Blocksize.
- *     sb->s_blocksize_bits    log2 of blocksize.
- *     <return>        0       Blocksize is valid.
- *     <return>        1       Blocksize is invalid.
- *
- * HISTORY
- *     July 1, 1997 - Andrew E. Mileski
- *     Written, tested, and released.
