Auto merge of #7160 - flip1995:field_reassign_macros, r=xFrednet,camsteffen

Don't trigger `field_reassign_with_default` in macros

Fixes #7155

Producing a good suggestion for this lint is already hard when no macros
are involved. With macros the lint message and the suggestion are just
confusing. Since both, producing a good suggestion and figuring out if
this pattern can be re-written inside a macro is nearly impossible, just
bail out.

changelog: [`field_reassign_with_default`] No longer triggers in macros

No that our reviewing queue is under control, I want to start hacking on Clippy myself again. Starting with an easy issue to get back in :)
