sched/smt: Always inline sched_smt_active()
[ 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
Fixes: 321a874a7ef8 ("sched/smt: Expose sched_smt_present static key")
