[PATCH] drm/panic: remove spurious empty line to clean warning

[Miguel Ojeda <ojeda@kernel.org>]

Clippy in the upcoming Rust 1.83.0 spots a spurious empty line since the
`clippy::empty_line_after_doc_comments` warning is now enabled by default
given it is part of the `suspicious` group [1]:

    error: empty line after doc comment
       --> drivers/gpu/drm/drm_panic_qr.rs:931:1
        |
    931 | / /// They must remain valid for the duration of the function call.
    932 | |
        | |_
    933 |   #[no_mangle]
    934 | / pub unsafe extern "C" fn drm_panic_qr_generate(
    935 | |     url: *const i8,
    936 | |     data: *mut u8,
    937 | |     data_len: usize,
    ...   |
    940 | |     tmp_size: usize,
    941 | | ) -> u8 {
        | |_______- the comment documents this function
        |
        = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#empty_line_after_doc_comments
        = note: `-D clippy::empty-line-after-doc-comments` implied by `-D warnings`
        = help: to override `-D warnings` add `#[allow(clippy::empty_line_after_doc_comments)]`
        = help: if the empty line is unintentional remove it

Thus remove the empty line.

I added the Fixes and stable tags since it would be nice to keep the 6.12 LTS
Clippy-clean (since that one is the first that supports several Rust compilers).
