mtd: powernv_flash: 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 platform remove callback a generic error message
by the device core is suppressed, nothing else changes.
This is a preparation for making platform remove callbacks return void.
