ixgbe: initialize interrupt throttle rate
This commit dropped the setting of the default interrupt throttle rate.

ixgbe: Introduce MSI-X queue vector code
The following patch adds it back. Without this the default value of 0
causes the performance of this card to be awful. Restoring these to the
default values yields much better performance.
This regression has been around since 2.6.25.
