[net 14/15] net/mlx5: prevent memory leak in mlx5_fpga_conn_create_cq

[Saeed Mahameed]

From: Navid Emamdoost <navid.emamdo...@gmail.com>

In mlx5_fpga_conn_create_cq if mlx5_vector2eqn fails the allocated
memory should be released.

Fixes: 537a50574175 ("net/mlx5: FPGA, Add high-speed connection routines")
