mmc: sdhci: Fix incorrect ADMA2 descriptor table size
The ADMA2 descriptor table size was being calculated incorrectly Fix it. Note that it has been wrong for a long time and likely has not caused any problems because of a combination of 1) not needing alignment descriptors for block operations 2) more memory being allocated than was requested 3) the use of SDHCI_QUIRK_NO_ENDATTR_IN_NOPDESC which does not use an extra descriptor for the end marker.
