mtd: hyperbus: Make hyperbus_unregister_device() return void

Browse source

[ Upstream commit 0c90466a79 ]

The only thing that could theoretically fail in that function is
mtd_device_unregister(). However it's not supposed to fail and when
used correctly it doesn't. So wail loudly if it does anyhow.

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

This is a preparation for making platform remove callbacks return void.
