sched/smt: Always inline sched_smt_active()

Browse Source 
[ Upstream commit 09f37f2d7b21ff35b8b533f9ab8cfad2fe8f72f6 ]

sched_smt_active() can be called from noinstr code, so it should always
be inlined.  The CONFIG_SCHED_SMT version already has __always_inline.
Do the same for its !CONFIG_SCHED_SMT counterpart.

Fixes the following warning:

  vmlinux.o: error: objtool: intel_idle_ibrs+0x13: call to sched_smt_active() leaves .noinstr.text section
