sd/sdhci.c: Only reset data_count on new commands
The data_count variable was being reset on every transfer, including
DMA transfer resumptions. This is incorrect, it should only be set
on a new command.
Manifests as a bug when using ADMA and there is a timer delay between
ADMA frames where the fifo is left in a non empty state.
