[ Upstream commit 98d068ab52b4b11d403995ed14154660797e7136 ]

The list rx_done would be initialized when the linking on occurs. Therefore, if a napi is scheduled without any linking on before, the following kernel panic would happen.

	BUG: unable to handle kernel NULL pointer dereference at 000000000000008
	IP: [<ffffffffc085efde>] r8152_poll+0xe1e/0x1210 [r8152]
	PGD 0
	Oops: 0002 [#1] SMP
