net/mlx5: fix detection of counter offset support
net/mlx5: fix detection of counter offset support

Currently, the counter offset support is discovered by creating the
rule with invalid offset counter and jump action in root table. If
the rule creation fails with EINVAL errno, that mean counter offset
is not supported in root table.

However, jump action may not be supported in some rdma-core version.
In this case, the discover code will not work properly.

This commits changes the jump action to generic drop action. That
makes the discover code to be more compatible.
