Ian Lepore dac94adb63 Do not overwrite the contents of BIO_WRITE buffers. SPI inherently
transfers data in both directions at once.  When writing to the device,
use a dummy buffer for the incoming data, not the same buffer as the
outgoing data.  Writes are done in FLASH_PAGE_SIZE chunks, which is only
256 bytes, so just put the dummy buffer into the softc.
