net: stmmac: selftests: Pass the IP proto mask in the TC selftest

The stmmac TC filtering rules have recently gained sanity checks to make
sure the passed keys and their respective masks are aligned with the HW
filtering abilities.

The stmmac selftests failed to pass the mask in the match data for L4
filtering tests, and are now failing consistently with -EINVAL :

$ ethtool -t eth1
[...]
23. L4 DA TCP Filtering          -22
24. L4 SA TCP Filtering          -22
25. L4 DA UDP Filtering          -22
26. L4 SA UDP Filtering          -22

Let's pass the ip_proto mask in the l4 filtering tests match data. Found
on imx8mp, which now have passing L4 tests :

$ ethtool -t eth1
[...]
23. L4 DA TCP Filtering          0
24. L4 SA TCP Filtering          0
25. L4 DA UDP Filtering          0
26. L4 SA UDP Filtering          0

While at it, initialize the masks and keys to avoid re-using whatever
was on the stack.
