net/mlx4: Fix the check in attaching steering rules
commit 6dc06c08bef1c746ff8da33dab677cfbacdcad32 upstream.
Our previous patch (cited below) introduced a regression
for RAW Eth QPs.
Fix it by checking if the QP number provided by user-space
exists, hence allowing steering rules to be added for valid
QPs only.
Fixes: 89c557687a32 ("net/mlx4_en: Avoid adding steering rules with invalid ring")
