ide: Convert to bdops->check_events()
Convert ->media_changed() to the new ->check_events() method. The
conversion is mostly mechanical. The only notable change is that
cdrom now doesn't generate any event if @slot_nr isn't CDSL_CURRENT.
It used to return -EINVAL which would be treated as media changed. As
media changer isn't supported anyway, this doesn't make any
difference.
This makes ide emit the standard disk events and allows kernel event
polling. Currently, only MEDIA_CHANGE event is implemented. Adding
support for EJECT_REQUEST shouldn't be difficult; however, given that
ide driver is already deprecated, it probably is best to leave it
alone.
