net/mlx4_core: fix memory leaks on error exit path 

The structures hca_param and func_cap are not being kfree'd on an error
exit path causing two memory leaks. Fix this by jumping to the existing
free memory error exit path.

Detected by CoverityScan, CID#1455219, CID#1455224 ("Resource Leak")

Fixes: c73c8b1e47 ("net/mlx4_core: Dynamically allocate structs at mlx4_slave_cap")
