block: remove unused bdrv_media_changed
This function is not used anywhere, so remove it.
Markus Armbruster adds:
The i82078 floppy device model used to call bdrv_media_changed() to
implement its media change bit when backed by a host floppy. This
went away in 21fcf36 "fdc: simplify media change handling".
Probably broke host floppy media change. Host floppy pass-through
was dropped in commit f709623. bdrv_media_changed() has never been
used for anything else. Remove it.
