net/mlx5: fix leak when starvation occurs

Browse Source 
The list of segments to free was wrongly manipulated ending by only freeing
the first segment instead of freeing all of them.  The last one still
belongs to the NIC and thus should not be freed.

Fixes: a1bdb71a32 ("net/mlx5: fix crash in Rx")
