[PATCH v2 3/5] Drivers: hv: ring_buffer: remove code duplication from hv_ringbuffer_peek/read()

hv_ringbuffer_peek() does the same as hv_ringbuffer_read() without advancing the read index. The only functional change this patch brings is moving hv_need_to_signal_on_read() call under the ring_lock but this function is just a couple of comparisons. Signed-off-by: Vitaly Kuznetsov ---
