Subject: rust: kernel: require `Send` for `Module` implementations

From: Wedson Almeida Filho <walmeida@xxxxxxxxxxxxx>

commit 323617f649c0966ad5e741e47e27e06d3a680d8f upstream.

The thread that calls the module initialisation code when a module is
loaded is not guaranteed [in fact, it is unlikely] to be the same one
that calls the module cleanup code on module unload, therefore, `Module`
implementations must be `Send` to account for them moving from one
thread to another implicitly.
