[PATCH 1/2] rust: doctest: fix incorrect pattern in replacement

[Gary Guo <gary@kernel.org>]

From: Gary Guo <gary@garyguo.net>

The `-> Result<(), impl core::fmt::Debug>` string is generated by rustdoc
and by adding "::" into the string it no longer finds anything, and making
the line useless. Remove the "::" in the pattern (but keep it in the
replacement result).

Fixes: de7cd3e4d638 ("rust: use absolute paths in macros referencing core and kernel")
