i40e/i40evf: Clean up a few things

1. There is no ixgbe_watchdog_task function in the driver, so change
   the comment to the correct function name, i40e_watchdog_subtask.
2. Remove num_msix_entries from interrupt set_up routine
   because it is never used.
3. Remove some TBD comments that are not needed.
