Alan Maguire 720c29fca9 libbpf: Propagate errors when retrieving enum value for typed data display ...

When retrieving the enum value associated with typed data during
"is data zero?" checking in btf_dump_type_data_check_zero(), the
return value of btf_dump_get_enum_value() is not passed to the caller
if the function returns a non-zero (error) value.  Currently, 0
is returned if the function returns an error.  We should instead
propagate the error to the caller.
