crypto: qat - fix bar discovery for c62x
Some accelerators of the c62x series have only two bars. This patch skips BAR0 if the accelerator does not have it. Cc: <stable@vger.kernel.org> Signed-off-by: Giovanni Cabiddu <giovanni.cabiddu@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
