drivers/net/lib8390: fix warning, trim trailing whitespace

fix

drivers/net/lib8390.c: In function ‘ei_tx_err’:
drivers/net/lib8390.c:556: warning: unused variable ‘ei_local’
drivers/net/lib8390.c: In function ‘ei_rx_overrun’:
drivers/net/lib8390.c:819: warning: unused variable ‘ei_local’

and also trim whitespace.

* Ok the logic behind the 8390 is very simple:

*
* Things to know
* - IRQ delivery is asynchronous to the PCI bus
* - Blocking the local CPU IRQ via spin locks was too slow
* - The chip has register windows needing locking work

* disable_irq_nosync_irqsave are disabling the local IRQ)

* Disable the IRQ (but not mask locally- someone seems to have

* We have to use disable_irq because otherwise you will get delayed

* Quite hairy but the chip simply wasn't designed for SMP and you can't
* even ACK an interrupt without risking corrupting other parallel
