Enable error-prone checking in the net-utils-framework-common

Enable error-prone checking in the net-utils-framework-common to
catch NullablePrimitive errors during build time.

Also fix any NullablePrimitive errors that are found in the
library classes.

Bug: 256991804
Test: Enable error-prone checking and check if the build fails
      with any NullablePrimitive errors. If it does, fix the
      errors and build again.
