[patch 1/5] x86/microcode/amd: Use correct per CPU ucode_cpu_info

[Thomas Gleixner <tglx@linutronix.de>]

find_blobs_in_containers() is invoked on every CPU but overwrites
uncoditionally ucode_cpu_info of CPU0.

Fix this by using the proper CPU data and move the assignment into the call
site apply_ucode_from_containers() so that the function can be reused.
