ixgbe: cleanup configuration of EITRSEL and VF reset path
This change is meant to cleanup some of the code related to SR-IOV and the
interrupt registers. Specifically I am moving the EITRSEL configuration
into the MSI-X configuration section instead of enablement. Also I am
fixing the VF shutdown path since it had operations in the incorrect order.
