crypto: qat - fix recovery flow for VFs

Browse Source 
When the PFVF protocol was updated to support version 5, i.e.
ADF_PFVF_COMPAT_FALLBACK, the compatibility version for the VF was
updated without supporting the message RESTARTING_COMPLETE required for
such version.

Add support for the ADF_VF2PF_MSGTYPE_RESTARTING_COMPLETE message in the
VF drivers. This message is sent by the VF driver to the PF to notify
the completion of the shutdown flow.
