From: Jacob Keller <[email protected]> A previous patch removed the pci_disable_device() call in .io_error_detected. This call corresponded to a pci_enable_device_mem() call within .io_slot_reset handler. Change the call here to a pci_reenable_device() so that it does not increment and leak the enable_cnt reference count for the device. Without this change, VF devices may fail during an unbind/bind, and we'll never zero the reference counter for the pci_dev structure.
