Code Issues Proposed changes

Select disk via kickstart

Browse Source 
If the boot_device and/or rootfs_device are not set on the kernel
cmdline detect them early in the kickstart script. This can help
solve the issue about which disk type is to be used.

Remove the older code for disk detection
Tested with both sda and nvme disk types
