[PATCH] x86/MCE: Get microcode revision from cpu_info instead of boot_cpu_data

Commit fa94d0c6e0f3 ("x86/MCE: Save microcode revision in machine check records") extended MCE entries to report the microcode revision taken from boot_cpu_data. Unfortunately, boot_cpu_data isn't updated on late microcode loading, thus making MCE entries slightly incorrect. Use cpu_info instead,
