block: add bdrv_reopen() support for raw hdev, floppy, and cdrom
For hdev, floppy, and cdrom, the reopen() handlers are the same as for the file reopen handler. For floppy and cdrom types, however, we keep O_NONBLOCK, as in the _open function. Signed-off-by: Jeff Cody <jcody@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
