Removing unused cnt increase from EMIT macro together
with cnt declarations. This was introduced in commit [1]
to ensure proper code generation. But that code was
removed in commit [2] and this extra code was left in.

[1] b52f00e6a715 ("x86: bpf_jit: implement bpf_tail_call() helper")
[2] ebf7d1f508a7 ("bpf, x64: rework pro/epilogue and tailcall handling in JIT")
