Mykyta Yatsenko 5f8d411729 bpf: Fix handling maps with no BTF and non-constant offsets for the bpf_wq ...

Fix handling maps with no BTF and non-constant offsets for the bpf_wq.

This de-duplicates logic with other internal structs (task_work, timer),
keeps error reporting consistent, and makes future changes to the layout
handling centralized.

Fixes: d940c9b94d ("bpf: add support for KF_ARG_PTR_TO_WORKQUEUE")
