sched/core: Convert vcpu_is_preempted() from macro to an inline function
Clang reports this warning:
kernel/locking/osq_lock.c:25:19: warning: unused function 'node_cpu' [-Wunused-function]
due to osq_lock() calling vcpu_is_preempted(node_cpu(node->prev))), but
vcpu_is_preempted() is compiled away. Fix it by converting the dummy
vcpu_is_preempted() from a macro to a proper static inline function.
