An spi_driver does not need to set an owner, it will be populated by the
driver core.

During the last close we are freeing spidev if spidev->spi is NULL, but
just before checking if spidev->spi is NULL we are dereferencing it.
Lets add a check there to avoid the NULL dereference.

Since spidev is no more allowed to use in DT and is really loudly warned about
it I'd like to add this compatible value.
