[PATCH net-next v4 4/4] rxtimestamp.c: add the test for SOF_TIMESTAMPING_OPT_RX_FILTER

[Jason Xing <kerneljasonxing@gmail.com>]

From: Jason Xing <kernelxing@tencent.com>

Test when we use SOF_TIMESTAMPING_OPT_RX_FILTER with software
or hardware report flag. The expected result is no rx timestamp
report.
