5.15-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit cf3515c556907b4da290967a2a6cbbd9ee0ee723 ]
The test is sending only one packet generated with mausezahn from $h1 to $h2. However, for some reason, it is testing for non-zero maximum occupancy in both the ingress pool of $h1 and $h2. The former only passes when $h2 happens to send a packet.
Avoid intermittent failures by removing unintentional test case regarding the ingress pool of $h1.
