ixgbe: Remove the Adaptative Interrupt Moderation code
* It didn't work correctly, the number of ixgbe interrupts per second
could become excessive
* Use a fixed rate for all interrupts, be they legacy, MSI or
MSI-X vectors. 8000 intr/s is a good default value.
* This change increases single stream tcp performance up to almost 50%
in the sending direction
