Currently, the counter offset support is discovered by creating the
rule with invalid offset counter and drop action in root table. If
the rule creation fails with EINVAL errno, that mean counter offset
is not supported in root table.
However, drop action may not be supported in some rdma-core version
in root table. In this case, the discover code will not work properly.
This commits changes flow attribute to egress. That removes all the
extra fate actions in the flow to avoid any unsupported fate actions
make the discover code fail time to time.
