Subject: [PATCH iwl-next v1] ixgbevf: remove unused fields from struct ixgbevf_adapter

Remove hw_rx_no_dma_resources and eitr_param fields from struct
ixgbevf_adapter since these fields are never referenced in the driver.

Note that the interrupt throttle rate is controlled by the
rx_itr_setting and tx_itr_setting variables.

This change simplifies the ixgbevf driver by removing unused fields,
which improves maintainability.
