crypto: qat - refactor fw config related functions
[ Upstream commit 2990d2edac6061c6f0f646a46e40957244be2268 ]
The logic that selects the correct adf_fw_config structure based on the
configured service is replicated twice in the uof_get_name() and
uof_get_ae_mask() functions. Refactor the code so that there is no
replication.
This does not introduce any functional change.
