pseries/plpks: fix error handling in plpks_read_var()
When a PLPKS variable is initialized without a policy and used to read an
object with the PLPKS_WRAPPINGKEY policy set, the hypervisor returns
H_AUTHORITY along with the object's policy. However, plpks_read_var()
currently treats this the same as any other H_AUTHORITY failure and returns
an error without propagating the policy information to the caller.
Distinguish this case from other H_AUTHORITY failures and propagate the
returned policy to the caller while preserving the authorization error.
Remove the explicit assignment of zero to rc on H_SUCCESS, as it is
redundant.
Also validate the PLPKS variable pointer before dereferencing it.
