[PATCH 1/2] mmc: fix error message for unaligned erase request

[Patrick Delaunay]

Fix the end address in the message for unaligned erase request in
mmc_berase() when start + blkcnt is aligned to erase_grp_size.

for example:
  - start = 0x2000 - 26
  - count = 26
  - erase_grp_size = 0x400

  Caution! Your devices Erase group is 0x400
  The erase range would be change to 0x2000~0x27ff

But no issue when the end address is not aligned, for example
  - start = 0x2000 - 2 * 26
  - count = 26
  - erase_grp_size = 0x400

  Caution! Your devices Erase group is 0x400
  The erase range would be change to 0x2000~0x23ff
