[jdk17u-dev] RFR: 8328864: NullPointerException in sun.security.jca.ProviderList.getService() [v2]

[Satyen Subramaniam]

> Backporting JDK-8328864: NullPointerException in sun.security.jca.ProviderList.getService(). Updated `getService` to check whether `getProvider` returns null when checking for preferred providers, continuing the loop if so. Added NullPreferredList test. Ran GHA Sanity Checks, local Tier 1 and 2 tests. Patch is clean.
