arch/x86/kernel/microcode*: Use pr_fmt() and remove duplicated KERN_ERR prefix
- Use #define pr_fmt(fmt) KBUILD_MODNAME ": " fmt - Remove "microcode: " prefix from each pr_<level> - Fix duplicated KERN_ERR prefix - Coalesce pr_<level> format strings - Add a space after an exclamation point No other change in output.
