Currently, we encounter segmentation fault when performing the following
test case:
1. Run testpmd application, config the flow filter rules then flush them
repeatedly.
2. Inject FLR concurrently every 5 second.
The calltrace info:
This GDB was configured as "aarch64-linux-gnu".
Reading symbols from ./testpmd...(no debugging symbols found)...done.

The root cause as follows：
In the '.flush' ops implementation function named hns3_flow_flush, By
the way the '.flush' ops is defined in the struct rte_flow_ops, if
failed to call hns3_clear_rss_filter, the out parameter error is not
set, and then the member variable name message in the struct error is
invalid(filled with 0x44444444 in port_flow_flush function of the
testpmd application), it leads to segmentation fault when format the
message.
We fixes it by filling error parameter when failure in calling static
function named hns3_clear_rss_filter in the the '.flush' ops
implementation function named hns3_flow_flush.
