we have been using this erase feature for a while, but it is
still not merged into the upstream mmc-utils. Especially, for
the customer, every time when they update the mmc-utils, they
should re-install this patch again, let's try to make this
erase command upstreamed in the mmc-utils.

We need to send 3 MMC commands and it is important that they
stay in sequence. Therefore we are using MMC_IOC_MULTI_CMD.
