commands: spi: fix NULL pointer dereference
The renaming of "master" to "controller" done in
812a9ddcdf211302a050cf8f61f7af577bc29a23
spi: Generalize SPI "master" to "controller"
breaks the spi command, because the spi.master pointer is not assigned.
The pointer is kept for backwards compatability.
Assign it, so that spi drivers that are still using "spi->master" can be
used.
