Normally, when the initrd is gone, we can't search it for microcode blobs to apply anymore. For that we need to stash away the patch in our own storage. And save_microcode_in_initrd_intel() looks like the proper place to do that from. So in order for early loading to work, invalidate the intel_ucode_patch pointer to the patch *before* scanning the initrd one last time. If the scanning code finds a microcode patch, it will assign that pointer again, this time with our own storage's address. This way, early microcode application during resume-from-RAM works too, even after the initrd is long gone.
