Don't ignore errors registering a device, ioport or mmio emulation
An error returned by device__register, kvm__register_mmio and
ioport__register means that the device will
not be emulated properly. Annotate the functions with __must_check, so we
get a compiler warning when this error is ignored.
And fix several instances where the caller returns 0 even if the function
failed.
Also make sure the ioport emulation code uses ioport_remove consistently.
