An issue has been discovered when running an IGT kunit test with a dynamic
sub-subtest specified: only the first kunit test case of a test suite can
be actually executed. Selecting a test case other than the first one
results in "Unloading test module failed, not executing more selftests."
message being displayed and no single test case (dynamic sub-subtest)
executed.
To avoid the failure from a consecutive module unload attempt after it has
been already unloaded, unload the test module neither after geting a list
of test cases, nor after each leaving of igt_dynamic() section, only as a
first step of each dynamic sub-subtest body.
