Memory allocated for new tx_ring and rx_ring leaks if
e1000_setup_XX_resources() fails.c Also this patch reduces stack usage
(removed tx_new and rx_new) and uses kzalloc instead kmalloc+memset(0)

We were plagued by our interrupt handler posting a watchdog event which
could occur when our adapter was going down in case a late packet arrived
just before e1000_down() finished. This caused the watchdog timer to start
after the NIC was down and keep rescheduling it every N seconds. Once
the driver unloaded it would panic.

With a patch, ethtool can now signify the driver to advertise more
than just a single speed/duplex setting. This allows you to tell the
card to advertise in 10/100 in any speed if you don't have a gigabit
switch for instance.

After studying the driver mac reset code it was found that there
were multiple race conditions possible to reset the unit twice or
bring it e1000_up() double. This fixes all occurences where the
driver needs to reset the mac.
We also remove irq requesting/releasing into _open and _close so
that while the device is _up we will never touch the irq's. This fixes
the double free irq bug that people saw.
To make sure that the watchdog task doesn't cause another race we let
it run as a non-scheduled task.
