[ Upstream commit 685814466bf8398192cf855415a0bb2cefc1930e ]
When zram test is skipped because of unmet dependencies and/or unsupported configuration, it exits with error which is treated as a fail by the Kselftest framework. This leads to false negative result even when the test could not be run.
Change it to return kselftest skip code when a test gets skipped to clearly report that the test could not be run.
Kselftest framework SKIP code is 4 and the framework prints appropriate messages to indicate that the test is skipped.
