x86: Clean up various simple wrapper functions
Remove unneeded variables and assignments.
While we are here, let's fix the following as well:
- Remove unnecessary parentheses
- Remove unnecessary unsigned-suffix 'U' from constant values
- Reword the comment in set_apic_id() (suggested by Thomas Gleixner)
