ide-cd: move request prep from cdrom_start_seek_continuation to rq issue path

... by factoring out the rq preparation code into a separate
function called in the request routine.  As a nice side effect,
this minimizes the IRQ handler execution time.

There should be no functionality change resulting from this patch.
