[PATCH v2] r8152: Add wake up function for RTL8153

In rtl8153_runtime_enable(), the runtime enable/disable logic for RTL8153
devices was incomplete, missing r8153_queue_wake() to enable or disable
the automatic wake-up function. A proper implementation can be found in
rtl8156_runtime_enable().

Add r8153_queue_wake(tp, true) if enable flag is set true, and add
r8153_queue_wake(tp, false) otherwise.
