rcutorture: Make rcu_fwd_cb_nodelay be a counter
Back when only one rcutorture kthread could do forward-progress testing,
it was just fine for rcu_fwd_cb_nodelay to be a non-atomic bool. It was
set at the start of forward-progress testing and cleared at the end.
But now that there are multiple threads, the value can be cleared while
one of the threads is still doing forward-progress testing. This commit
therefore makes rcu_fwd_cb_nodelay be an atomic counter, replacing the
WRITE_ONCE() operations with atomic_inc() and atomic_dec().
