[U-Boot] [PATCH] mmc: Fix error in RPMB code

[Marek Vasut <marex@denx.de>]

Since we do not build any board with CONFIG_SUPPORT_EMMC_RPMB , this
piece of code evaded conversion. Fix the following compiler error:

cmd/mmc.c: In function 'do_mmcrpmb':
cmd/mmc.c:316:32: error: 'struct blk_desc' has no member named 'part_num'
  original_part = mmc->block_dev.part_num;
                                ^
