[PATCH] x86, procfs: remove condition for show_cpuinfo_core()

[HATAYAMA Daisuke]

show_cpuinfo_core() has displayed cpu core information only if the
number of threads per a whole cores is strictly larger than 1. But
this condition doesn't care about the number of sockets. This doesn't
cover, for example, the system with two logical cpus consisting of two
sockets and a single core on each socket.

However, this information is useful even if there's only 1 thread. So,
how to fix it here is to simply remove the condition, instead of
fixing the condition.
