bpf: Avoid warning on unexpected map for tail call

Before handling the tail call in record_func_key(), we check that the
map is of the expected type and log a verifier error if it isn't. Such
an error however doesn't indicate anything wrong with the verifier. The
check for map<>func compatibility is done after record_func_key(), by
check_map_func_compatibility().

Therefore, this patch logs the error as a typical reject instead of a
verifier error.

Fixes: 0df1a55afa83 ("bpf: Warn on internal verifier errors")
