net/mlx5: fix kvfree of uninitialized pointer spec
Currently when a call to esw_vport_create_legacy_ingress_acl_group
fails the error exit path to label 'out' will cause a kvfree on the
uninitialized pointer spec. Fix this by ensuring pointer spec is
initialized to NULL to avoid this issue.
Addresses-Coverity: ("Uninitialized pointer read")
Fixes: 10652f39943e ("net/mlx5: Refactor ingress acl configuration")
