[dpdk-stable] [PATCH] vdpa/mlx5: fix completion queue assertion

[Matan Azrad]

The CQ configuration enables the collapse feature in HW what cause HW to
write all the completions in the first CQE.
When this feature is enabled the HW doesn't switch the owner bit when it
starts a new cycle of the CQ, not like working without the collapse
feature.

The current SW CQ polling wrongly added an assertion to validate the
owner bit switch what causes a panic in debug mode.

Remove the aforementioned assertion.
