x86/pkru: Provide pkru_get_init_value()
When CONFIG_X86_INTEL_MEMORY_PROTECTION_KEYS is disabled then the following
code fails to compile:
if (cpu_feature_enabled(X86_FEATURE_OSPKE)) {
u32 pkru = READ_ONCE(init_pkru_value);
..
}
because init_pkru_value is defined as '0' which makes READ_ONCE() upset.
Provide an accessor macro to avoid #ifdeffery all over the place.
