Subject: [PATCH net 1/3] selftests: mlxsw: sharedbuffer: Remove h1 ingress test case

From: Danielle Ratson <danieller@...dia.com>

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.
