r8169: improve RTL8168b FIFO overflow workaround

Browse Source 
[ Upstream commit 6b02e407cb ]

So far only the reset bit it set, but the handler executing the reset
is not scheduled. Therefore nothing will happen until some other action
schedules the handler. Improve this by ensuring that the handler is
scheduled.
