[PATCH 5.10 048/145] selftests: mlxsw: Set headroom size of correct port

[Greg Kroah-Hartman]

From: Ido Schimmel <idosch@xxxxxxxxxx>

[ Upstream commit 2ff2c7e274392871bfdee00ff2adbb8ebae5d240 ]

The test was setting the headroom size of the wrong port. This was not
visible because of a firmware bug that canceled this bug.

Set the headroom size of the correct port, so that the test will pass
with both old and new firmware versions.
