crypto: qat - remove unnecessary tests to detect PFVF support

Browse Source 
Previously, the GEN4 host driver supported SR-IOV but had no working
implementation of the PFVF protocol to communicate with VF drivers.
Since all the host drivers for QAT devices now support both SR-IOV and
PFVF, remove the old and unnecessary checks to test PFVF support.
