"File 'cd0' exists but cannot be stated" fix for QNX 6.x

[Dmitry Alexeyev <dmi_a qnx org ru>]

Hello!

QNX 6.x CDROM driver always keeps file '/fs/cd0', which exists, but
cannot be stat()'ed if there's no disk in drive.
a.e. you may see something like that (without mc running):

# ls -la /fs
ls: No such device or address (/fs/cd0)
total 96
drwxrwxrwx 49 root      root          32768 Oct 08 22:37 hd0-dos

QNX 6.x automatically mounts all available filesystems under /fs, so
it is used very often and "cannot be stated" messages becomes very
annoying.

Here's a small hack against it:
