disk: Replace transform_sector() function with grub_disk_to_native_sector()

Browse Source 
The transform_sector() function is not very clear in what it's doing
and confusing. The GRUB already has a function which is doing the same
thing in a very self explanatory way, i.e., grub_disk_to_native_sector().
So, it's much better to use self explanatory one than transform_sector().
