mmc: mxcmmc: fix falling back to PIO
commit e58f516ff4730c4047c3f104b061f7a03e9a263c upstream.
When we can't configure the dma channel we want to fall
back to PIO. We do this by setting host->do_dma to zero.
This does not work as do_dma is used to see whether dma
can be used for the current transfer. Instead, we have
to set host->dma to NULL.
