mmcsd_removed will be called if the card is in invalid state.
This can happen if the card is bad, or vibrations causes a power
loss.
mmcsd_removed resets:
priv->capacity = 0; /* Capacity=0 sometimes means no media */
priv->blocksize = 0;
priv->probed = false;
priv->mediachanged = false;
priv->wrbusy = false;
priv->type = MMCSD_CARDTYPE_UNKNOWN;
priv->rca = 0;
priv->selblocklen = 0;
priv->widebus = false;
If blocksize is set to 0 will cause the log2 to result
in an infinate loop in some drivers.
IS_EMPTY will check for priv->type = MMCSD_CARDTYPE_UNKNOWN
and return ENODEV.
