cmd: mmc: fix help and parameter verification with MMC_SPEED_MODE_SET not set
Currently help and parameter scanning does not check whether the feature
is enabled or not. This leads to wrong expectations based on help output
and no clear sign why the mmc dev and mmc rescan do not enforce the
supplied mode.
Fixes: 19f7a34a4642 ("mmc: Add support for enumerating MMC card in a given mode using mmc command")
