Subject: [PATCH] net/mlx5: fix mlx5 device start failure

From: Rongwei Liu <rongweil at nvidia.com>

When devargs "allow_duplicate_pattern=0" is specified, PMD won't
allow duplicated flows to be inserted and return EEXIST as rte_errno.

The queue/RSS split table is shared globally by all representors and
PMD didn't prepend port information into it, so all the following ports
tries to insert the same flows and cause PMD insertion failure.

Using the hash list to manage it can solve the issue.
