[PATCH 2/8] rust: pin-init: internal: suppress `non_snake_case` lint in `#[pin_data]`

[Gary Guo]

From: Mirko Adzic <adzicmirko97@xxxxxxxxx>

Allows `non_snake_case` lint on struct fields generated by `#[pin_data]`.

Since the same warning will be reported by the compiler on the struct
definition, having extra warnings for the generated code is unnecessary
and confusing.
