[Intel-wired-lan] [next PATCH S76-V2 03/13] i40e: move enabling icr0 into i40e_update_enable_itr

[Alice Michael]

From: Jacob Keller <jacob.e.keller at intel.com>

If we don't have MSI-X enabled, we handle interrupts on all icr0. This
is a special case, so let's move the conditional into
i40e_update_enable_itr() in order to make i40e_napi_poll easier to
read about.
