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)));
