Subject: 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)
