arch/x86/smbios: fix extended CPUID level check logic
Before the cpuid(0x80000001) read in smbios_write_type4, it was
previously checked in a slightly convoluted way if the result from
cpu_cpuid_extended_level was larger than 0x80000001, but the check
should be if it is larger or equal to 0x80000001.
