x86: Remove unnecessary check in detect_ht()

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.
