efi: Reorder pr_notice() with add_device_randomness() call

Browse Source 
Currently, when we receive a random seed from the EFI stub, we call
add_device_randomness() to incorporate it into the entropy pool, and
issue a pr_notice() saying we are about to do that, e.g.,

  [    0.000000] efi:  RNG=0x87ff92cf18
  [    0.000000] random: fast init done
  [    0.000000] efi: seeding entropy pool

Let's reorder those calls to make the output look less confusing:

  [    0.000000] efi: seeding entropy pool
  [    0.000000] efi:  RNG=0x87ff92cf18
  [    0.000000] random: fast init done
