x86: fix arch/x86/kernel/cpu/mtrr/main.c warning

fix this warning reported by Andrew Morton:

> arch/x86/kernel/cpu/mtrr/main.c: In function 'mtrr_bp_init':
> arch/x86/kernel/cpu/mtrr/main.c:1170: warning: 'extra_remove_base' may be used uninitialized in this function

the warning is bogus but the logic that prevents uninitialized use
is a bit convoluted so simplify it all.
