Subject: [PATCH net-next 1/2] be2net: remove unused local rsstable array

Remove rsstable array and its initialization from be_set_rss_hash_opts().
The array became unused after "e255787 be2net: Support for configurable
RSS hash key". The initial RSS table is now filled and stored for later
usage during Rx queue creation.
