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 IOC controllers.

With this patch, driver will 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 after controller comes back to ready state.

Applied to 5.13/scsi-queue, thanks!
