crypto: qat - fix ring to service map for dcc in 4xxx
[ Upstream commitdf018f8200
] 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. Fixes:a238487f79
