While diag reset is in progress there is short duration where all access to controller's PCI config space from the host needs to be blocked. This is due to a hardware limitation of the IOC controllers. Block all access to controller's config space from userland applications by calling pci_cfg_access_lock() while diag reset is in progress and unlocking it again after the controller comes back to ready state.
