The commit "crypto: qat - generate dynamically arbiter mappings"
introduced a regression on qat_402xx devices.
This is reported when the driver probes the device, as indicated by
the following error messages:
4xxx 0000:0b:00.0: enabling device (0140 -> 0142)
4xxx 0000:0b:00.0: Generate of the thread to arbiter map failed
4xxx 0000:0b:00.0: Direct firmware load for qat_402xx_mmp.bin failed with error -2
The root cause of this issue was the omission of a necessary function
pointer required by the mapping algorithm during the implementation.
Fix it by adding the missing function pointer.
