x86: make "apic" an early_param() on 32-bit, NULL check
Cyrill Gorcunov observed: > you turned it into early_param so now it's NULL injecting vulnerabled. > Could you please add checking for NULL str param? fix that. Also, change the name of 'str' into 'arg', to make it more apparent that this is an optional argument that can be NULL, not a string parameter that is empty when unset.
