x86/mm/pat: Replace cpu_has_pat with boot_cpu_has()
commit d63dcf49cf5ae5605f4d14229e3888e104f294b1 upstream.
Borislav Petkov suggested:
> Please use on init paths boot_cpu_has(X86_FEATURE_PAT) and on fast
> paths static_cpu_has(X86_FEATURE_PAT). No more of that cpu_has_XXX
> ugliness.
Replace the use of cpu_has_pat on init paths with boot_cpu_has().
