[Bug 574690] [NEW] cdrom device names do not start from /dev/cdrom

[jargon at iki.fi]

Public bug reported:

On my system replacing a broken DVD device caused first cd-rom/dvd
device being listed as /dev/cdrom1 instead of /dev/cdrom.

This is a problem because a lot of application assume that first CD
device is at /dev/cdrom and fail to iterate devices if first device is
at /dev/cdrom1. Of course user can manually change applications to use
/dev/cdrom1, but average user does not realize the problem.

I have been using Linux for 10 years, and it took me 10 minutes to
figure out what's wrong.

Steps to reproduce:

1. Remove current CDROM or DVD device
2. Install new one, the new one will be at /dev/cdrom1 even as old one is removed

Suggested fix:
1. Make sure that first CDROM device is always accessible from /dev/cdrom
