This audits the mount system call, rather than the mount command.

My guess is that the mount command is doing its own check and is
failing before it attempts the mount system call.  If you run

$ strace mount /dev/hdc /dev/cdrom

you'll see the system calls that are executed.
I suspect there is no mount system call in the output.
