spi flash: fix crash due to spi flash miscommunication
Higher spi flash layers expect to be given back a pointer that was
malloced so that it can free the result, but the lower layers return
a pointer that is in the middle of the malloced memory. Reorder the
members of the lower spi structures so that things work out.
