Subject: [PATCH] net/mlx5: fix RSS key length query

[ upstream commit e7041f5529d129eef57d6ac9405a510b1df69ae4 ]

The RSS key length returned by rte_eth_dev_info_get command was taken
from the
PMD private structure. This structure initialization was done only after
the port configuration.

Considering Mellanox device supports only 40B long RSS key, reporting
the fixed number instead.

Fixes: 29c1d8bb3e79 ("net/mlx5: handle a single RSS hash key for all protocols")
