Subject: [PATCH] dracut: Do not create early_cpio if no suitable microcode

 exist in hostonly case

Intel microcodes only exist for very specific family/model/stepping CPUs.

If no microcode gets added, there is no need to create an empty

(only directories) cpio later that gets glued to the initrd.

This also fixes:

*** Constructing GenuineIntel.bin ****

cat: /lib/firmware/intel-ucode/06-3c-03: No such file or directory

in hostonly mode if there is no suitable microcode for the CPU.
