ena: Disable meta descriptor caching for netmap

If LLQ is being used, `ena_tx_ctx.meta_valid` must stay enabled. This
fixes netmap support on latest generation ENA HW and aligns it with the
core driver behavior.

As netmap doesn't support any csum offloads, the
`adapter->disable_meta_caching` value can be simply passed to the HW.
