igt/drv_module_reload: Reload with full mmio-debugging
mmio-debugging is lazy, we only turn on per-access checking after
a periodic check to see if an error has been flagged. If we load the
module with mmio_debug, we can validate that no such errors occur during
module_init, which is one of the trickier times to get right (having to
balance sanitization of existing HW state with our own).
