[PATCH] net/mlx5/hws: fix cap check for hash calc

[Maayan Kashani]

From: Itamar Gozlan <igozlan at nvidia.com>

Some cases are not supported for rule hash calculation. For example
when the matcher defined as FW matcher, or is the hash type is different
than CRC32. One case is when the distribute mode is not by hash, the
previous condition checked a wrong capability, while this commit fixes
it to the correct check.
