pseries/plpks: validate input to plpks_signed_update_var()
plpks_signed_update_var() dereferences the supplied PLPKS variable pointer
without validating it. A NULL argument could therefore result in a NULL
pointer dereference.
Reject a NULL pointer argument with -EINVAL.
Fixes: 899d9b8fee66 ("powerpc/pseries: Implement signed update for PLPKS objects")
