ACPI: AGDI: Improve error reporting for problems during .remove()
Returning an error value in a platform driver's remove callback results in
a generic error message being emitted by the driver core, but otherwise it
doesn't make a difference. The device goes away anyhow.
So instead of triggering the generic platform error message, emit a more
helpful message if a problem occurs and return 0 to suppress the generic
message.
This patch is a preparation for making platform remove callbacks return
void.
