Subject: rust: page: mark Page::nid as inline
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When building the kernel, the following Rust symbol is generated:

  $ nm vmlinux | grep ' _R'.*Page | rustfilt
  <kernel::page::Page>::nid

`Page::nid` is a trivial wrapper around the C function `page_to_nid`.  It
does not make sense to go through a trivial wrapper for this function, so
mark it inline.

This follows commit 878620c5a93a ("rust: page: optimize rust symbol
generation for Page"), which did the same for `alloc_page` and `drop`.
