When tracing a kernel function with arg type is u32*, btf_ctx_access() would report error: arg2 type INT is not a struct. The commitbb6728d756("bpf: Allow access to int pointer arguments in tracing programs") added support for int pointer, but did not skip modifiers before checking it's type. This patch fixes it.
