crypto: qat - fix duplicate restarting msg during AER error

[ Upstream commit 961ac9d97be72267255f1ed841aabf6694b17454 ]

The restarting message from PF to VF is sent twice during AER error
handling: once from adf_error_detected() and again from
adf_disable_sriov().
This causes userspace subservices to shutdown unexpectedly when they
receive a duplicate restarting message after already being restarted.

Avoid calling adf_pf2vf_notify_restarting() and
adf_pf2vf_wait_for_restarting_complete() from adf_error_detected() so
that the restarting msg is sent only once from PF to VF.
