sfc: release encap match in efx_tc_flow_free()

When force-freeing leftover entries from our match_action_ht, call
 efx_tc_delete_rule(), which releases all the rule's resources, rather
 than open-coding it.  The open-coded version was missing a call to
 release the rule's encap match (if any).
It probably doesn't matter as everything's being torn down anyway, but
 it's cleaner this way and prevents further error messages potentially
 being logged by efx_tc_encap_match_free() later on.
Move efx_tc_flow_free() further down the file to avoid introducing a
 forward declaration of efx_tc_delete_rule().
