Copy trait is derived when a struct contains __IncompleteArrayField

[leeopop]

I have this error with generated code.

6948 |     pub field: __IncompleteArrayField<rte_acl_field>,
     |     ------------------------------------------------ this field does not implement `Copy`

While the generated rte_acl_field is

#[repr(C)]
#[derive(Debug, Copy)]
pub struct rte_acl_field {
    pub value: rte_acl_field_types,
    pub mask_range: rte_acl_field_types,
}

I think a00e8b0
affects the result.

I check that 7d995d7 did not cause problems.
You may refer https://github.com/ANLAB-KAIST/rust-dpdk this repository to reproduce my result or put this usage scenario into test cases.
