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.

  *              - 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)
