Feng Zhou 52c3d68d99 bpf/btf: Fix is_int_ptr() ...

[ Upstream commit 91f2dc6838c19342f7f2993627c622835cc24890 ]

When tracing a kernel function with arg type is u32*, btf_ctx_access()
would report error: arg2 type INT is not a struct.

The commit bb6728d756 ("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.
