This addresses other oopsing paths in "spidev" by changing how it manages
refcounting. It decouples the lifecycle of the per-device data from the
class device (not just the spi device):
- Use class_{create,destroy} not class_{register,unregister}.
- Use device_{create,destroy} not device_{register,unregister}.
- Free the per-device data only when TWO conditions are true:
* Driver is unbound from underlying SPI device, and
* Device is no longer open (new)
Also, spi_{get,set}_drvdata not dev_{get,set}_drvdata for simpler code.
