r8152: re-schedule napi for tx


[ Upstream commit 248b213a ]

Re-schedule napi after napi_complete() for tx, if it is necessay.

In r8152_poll(), if the tx is completed after tx_bottom() and before
napi_complete(), the scheduling of napi would be lost. Then, no
one handles the next tx until the next napi_schedule() is called.
