crypto: qat - fix ring to service map for dcc in 4xxx

If a device is configured for data compression chaining (dcc), half of the
engines are loaded with the symmetric crypto image and the rest are loaded
with the compression image.
However, in such configuration all rings can handle compression requests.

Fix the ring to service mapping so that when a device is configured for
dcc, the ring to service mapping reports that all rings in a bank can
be used for compression.
