[PATCH v6 21/26] powerpc/pseries: Clarify warning when PLPKS password already set

[Andrew Donnellan]

When the H_PKS_GEN_PASSWORD hcall returns H_IN_USE, operations that require
authentication (i.e. anything other than reading a world-readable variable)
will not work.

The current error message doesn't explain this clearly enough. Reword it
to emphasise that authenticated operations will fail.
