tools: bpftool: print only one error message on byte parsing failure

Browse Source 
Make error messages more consistent. Specifically, when bpftool fails at
parsing map key bytes, make it print a single error message to stderr
and return from the function, instead of (always) printing a second
error message afterwards.
