pybind/rbd: don't produce info on errors in aio_mirror_image_get_info()

Check completion return value before attemting to decode c_info.
Otherwise we are guaranteed to access invalid memory in decode_cstr()
while trying to compute global_id string length when the client is
blocklisted for example.
