r8152: fix the setting of detecting the linking change for runtime suspend
1. Rename r8153b_queue_wake() to r8153_queue_wake(). 2. Correct the setting. The enable bit should be 0xd38c bit 0. Besides, the 0xd38a bit 0 and 0xd398 bit 8 have to be cleared for both enabled and disabled. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S. Miller <davem@davemloft.net>
