[PATCH] fix subarchitecture breakage with CONFIG_SCHED_SMT

Commit 1e9f28fa1eb9773bf65bae08288c6a0a38eef4a7 ("[PATCH] sched: new
sched domain for representing multi-core") incorrectly made SCHED_SMT
and some of the structures it uses dependent on SMP.

However, this is wrong, the structures are only defined if X86_HT, so
SCHED_SMT has to depend on that as well.

The patch broke voyager, since it doesn't provide any of the multi-core
or hyperthreading structures.
