x86/microcode/intel: Pass the microcode revision to print_ucode_info() directly

print_ucode_info() takes a struct ucode_cpu_info pointer as parameter.
Its sole purpose is to print the microcode revision.

The only available ucode_cpu_info always describes the currently loaded
microcode revision. After a microcode update is successful, this is the
new revision, or on failure it is the original revision.

In preparation for future changes, replace the struct ucode_cpu_info
pointer parameter with a plain integer which contains the revision
number and adjust the call sites accordingly.

No functional change.
