Store the RSS key inside struct igc_adapter and introduce the
igc_write_rss_key() helper function. This allows the driver to program
the RSSRK registers using a persistent RSS key, instead of using a
stack-local buffer in igc_setup_mrqc().

This is a preparation patch for adding RSS key get/set support in
subsequent changes, and no functional change is intended in this patch.
