<div class='commit-subject'>e1000: use disable_hardirq() for e1000_netpoll()</div><div class='commit-msg'>In commit 02cea3958664 ("genirq: Provide disable_hardirq()")
Peter introduced disable_hardirq() for netpoll, but it is forgotten
to use it for e1000.

This patch changes disable_irq() to disable_hardirq() for e1000.
