[PATCH] env: mmc: specify that the address is a block address when erasing

[Quentin Schulz]

From: Quentin Schulz <quentin.schulz at cherry.de>

I got very confused by the address printed when erasing the environment
because I clearly didn't remember setting it at that location.

It turns out, it's the block offset and not the byte offset that is
reported, so let's make this a bit more obvious to the user.

Another option would be to report the byte offset by multiplying
blk_start by desc->blksz I guess. The result needs to be stored in a u64
though instead of uint otherwise we'll be limited to 4GiB offset (which
should be fine in most cases but eh).
