Revert "[MTD] m25p80.c code cleanup"

Browse source 
This reverts commit 75d0ee2202.

Although it seems ObviouslyCorrect™, the spi_write() call uses DMA,
while spi_write_then_read() does not. Since our buffer is on the stack,
we must use the latter even though we don't actually want to read
anything back.
