Don't check if a drive is a tape drive unless needed

[Garrett Kajmowicz]

By default fdisk on performs a sanity check on the type of drive in the event 
that it's autoselected through fdisk -l
In short, let's do compile-time determination instead of run-time 
determination of which code needs to be executed.

Also, is the code for checking if something is a CDROM or a tape drive still 
important?  The comments in the code note that running fdisk -l on an audio 
cdrom drive could cause it to crash.  Event if it still occurs, do we really 
care?
