[PATCH] x86/microcode: Add microcode_loader_disabled() storage class for the !CONFIG_MICROCODE case

[Ingo Molnar <mingo@kernel.org>]

Fix this build bug:

  ./arch/x86/include/asm/microcode.h:27:13: warning: no previous prototype for ‘microcode_loader_disabled’ [-Wmissing-prototypes]

by adding the 'static' storage class to the !CONFIG_MICROCODE 
prototype.

Also, while at it, add all the other storage classes as well for this 
block of prototypes, 'extern' and 'static', respectively.

( Omitting 'extern' just because it's technically not needed
  is a bad habit for header prototypes and leads to bugs like
  this one. )
