e1000e: fix e1000_netpoll(), remove extraneous e1000_clean_tx_irq() call
Evgeniy Polyakov noticed that drivers/net/e1000e/netdev.c:e1000_netpoll()
was calling e1000_clean_tx_irq() without taking the TX lock.
David Miller suggested to remove the call altogether: since in this
callpah there's periodic calls to ->poll() anyway which will do
e1000_clean_tx_irq() and will garbage-collect any finished TX ring
descriptors.
This fix solved the e1000e+netconsole crashes i've been seeing:
