doc attributes on reexport of type are copied to inherent impls

[rodrimati1992]

With a foo_lib dependency, I tried documenting the bar_lib crate with this code:

/// These are the docs for Foo.
pub use foo_lib::Foo;

I expected to see this happen: the documentation appears only for the type.

Instead, this happened: the documentation appears on the type's inherent impl block as well as the type.
