[PATCH] net/mlx5: fix error infomation missing

[Suanming Mou]

While mlx5_hlist_create() failed, the rte_flow_error was not filled
with the corresponding error information.

This commit adds the missing rte_flow_error_set() for the failure case.

Fixes: f3020a331dca ("net/mlx5: optimize hash list table allocate on demand")
