x86/microcode/intel: hide warning on high order allocation for microcode
area
Microcode blob can require a page of 3rd order and loading microcode
data is done using "wrmsr" asm instruction, so we cannot substitute
kmalloc() with kvmalloc() here.
Let's just hide the warning for this scenario, microcode update is a
rare operation anyway.
