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
