r8152: check rx after napi is enabled
[ Upstream commit 7489bdad ] Schedule the napi after napi_enable() for rx, if it is necessary. If the rx is completed when napi is disabled, the sheduling of napi would be lost. Then, no one handles the rx packet until next napi is scheduled. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S.
