x86: Remove unnecessary check in detect_ht()
This patch removes a check that causes incorrect scheduler domain setup (SMP instead of SMT) and bootlog warning messages when cpuid extensions for topology enumeration are not supported and the number of processors reported to the OS is smaller than smp_num_siblings.
