[dpdk-dev] [PATCH v2 3/4] net/mlx5: fix description of function return value

[Dekel Peled <dekelp@mellanox.com>]

Return value of function mlx5_rxq_releasable() was not described
correctly in function description.

This patch updates the description to correctly describe the optional
return values.
