Subject: [PATCH AUTOSEL 5.15 22/69] selftests: mlxsw: resource_scale: Allow skipping a test

From: Petr Machata <petrm@...dia.com>

[ Upstream commit 8cad339db339a39cb82b1188e4be4070a433abac ]

The scale tests are currently testing two things: that some number of
instances of a given resource can actually be created; and that when an
attempt is made to create more than the supported amount, the failures are
noted and handled gracefully.

Sometimes the scale test depends on more than one resource. In particular,
a following patch will add a RIF counter scale test, which depends on the
number of RIF counters that can be bound, and also on the number of RIFs
that can be created.

When the test is limited by the auxiliary resource and not by the primary
one, there's no point trying to run the overflow test, because it would be
testing exhaustion of the wrong resource.

To support this use case, when the $test_get_target yields 0, skip the test
instead.
