ixgbe: fix reconfiguration of Rx method

The scattered_rx configuration is updated in dev_start().
For the execution sequence "stop, re-configure and then re-start",
it expects using the new configuration.
But during re-configure, the stored data may still be the old one.
The patch clean the configuration anyway in dev_stop().
So that make sure always get the best Rx routine.
