Auto merge of rust-lang#11473 - Alexendoo:format-args-span-parents, r=dswij

Ignore span's parents in `collect_ast_format_args`/`find_format_args`

Fixes rust-lang#11470, covers some cases missed by rust-lang#10980

Can't have a test yet because of rust-lang#11126 but it works locally

changelog: none

r? `@dswij`
