mtd: mchp48l640: Warn about failure to unregister mtd device 



mtd_device_unregister() shouldn't fail. Wail loudly if it does anyhow.

This matches how other drivers (e.g. nand/raw/nandsim.c) use
mtd_device_unregister().

By returning 0 in the spi remove callback a generic error message by the
spi framework (and nothing else) is suppressed.
