drm/panic: correctly indent continuation of line in list item

drm/panic: correctly indent continuation of line in list item

commit 5bb698e6fc514ddd9e23b6649b29a0934d8d8586 upstream.

It is common practice in Rust to indent the next line the same amount of
space as the previous one if both belong to the same list item. Clippy
checks for this with the lint `doc_lazy_continuation`.

    error: doc list item without indentation
    --> drivers/gpu/drm/drm_panic_qr.rs:979:5
        |
    979 | /// conversion to numeric segments.
        |     ^
        |
        = help: if this is supposed to be its own paragraph, add a blank line
        = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#doc_lazy_continuation
        = note: `-D clippy::doc-lazy-continuation` implied by `-D warnings`
        = help: to override `-D warnings` add `#[allow(clippy::doc_lazy_continuation)]`
    help: indent this line
        |
    979 | ///   conversion to numeric segments.
        |     ++

Indent the offending line by 2 more spaces to remove this Clippy error.
