erts: Fix bug of scheduling a suspended process
This is a race that can cause RUNNING (instead of RUNNING_SYS) set on a SUSPENDED process. The effect of this race happening is probably quite benign. The bug was discovered by process_SUITE:processes_gc_trap on debug VM crashing on last assert in schedule(): /* Never run a suspended process */ ASSERT(!(ERTS_PSFLG_SUSPENDED & erts_smp_atomic32_read_nob(&p->state)));
