mmc: block: blk-mq: Stop using legacy recovery
There are only a few things the recovery needs to do. Primarily, it just
needs to:
Determine the number of bytes transferred
Get the card back to transfer state
Determine whether to retry
There are also a couple of additional features:
Reset the card before the last retry
Read one sector at a time
The legacy code spent much effort analyzing command errors, but commands
fail fast, so it is simpler just to give all command errors the same number
of retries.
