tools/bpftool: Fix skeleton codegen

Remove unnecessary check at the end of codegen() routine which makes codegen()
to always fail and exit bpftool with error code. Positive value of variable
n is not an indicator of a failure.

Fixes: 2c4779eff837 ("tools, bpftool: Exit on error in function codegen")
