[PATCH bpf-next] bpf: fix build on architectures with special bpf_user_pt_regs_t

Architectures like s390, powerpc, arm64, riscv have speical definition of bpf_user_pt_regs_t. So we need to cast the pointer before passing it to bpf_get_stack(). This is similar to bpf_get_stack_tp(). Fixes: 03d42fd2d83f ("bpf: Separate bpf_get_[stack|stackid] for perf events BPF") Reported-by:
