spi: Clean up probe and remove functions
While backporting 33cf00e5 ("spi: attach/detach SPI device to the ACPI
power domain"), I noticed that the code changes were suboptimal:
* Why use &spi->dev when we have dev at hand?
* After fixing the above, spi is used only once, so we don't really
need a local variable for it.
This results in the following clean-up.
