[ Upstream commit 5c04243a56a7977185b00400e59ca7e108004faf ]
Media event code 3 is defined in the MMC-6 spec as follows:
"MediaRemoval: The media has been removed from the specified slot, and the Drive is unable to access the media without user intervention. This applies to media changers only."
This indicated that treating the condition as an EJECT_REQUEST was appropriate. However, doing so had the unfortunate side-effect of causing the drive tray to be physically ejected on resume. Instead treat the event as a MEDIA_CHANGE request.
