crypto: qat - change bufferlist logic interface
jira LE-1907 Rebuild_History Non-Buildable kernel-5.14.0-284.30.1.el9_2 commit-author Giovanni Cabiddu <giovanni.cabiddu@intel.com> commit 3ed330d The functions qat_alg_sgl_to_bufl() and qat_alg_free_bufl() take as argument a qat_crypto_instance and a qat_crypto_request structure. These two structures are used only to get a reference to the adf_accel_dev and qat_crypto_request_buffs. In order to reuse these functions for the compression service, change the signature so that they take adf_accel_dev and qat_crypto_request_buffs.
