ARM: 6642/1: mmci: calculate remaining bytes at error correctly

Browse source

The MMCIDATACNT register contain the number of byte left at error
not the number of words, so loose the << 2 thing. Further if CRC
fails on the first block, we may end up with a negative number
of transferred bytes which is not good, and the formula was in
wrong order.
