[PATCH] mtd: dataflash: Remove use of tx_dma

[Mark Brown]

We are trying to remove the legacy tx_dma and rx_dma fields from the
spi_transfer structure. Currently dataflash uses tx_dma but only to make
sure that it's set to 0 so we can remove this use by replacing with a
zero initialisation of the entire spi_transfer struct.
