rumpdisk: Defer hardware initialization to avoid deadlock on stat.
Currently, rumpdisk initializes the Rump kernel and probes the PCI bus
immediately during main(). When rumpdisk is configured as a passive translator
(e.g., for /dev/rumpusbdisk), a simple stat or ls on the node triggers
translator startup. This causes a second Rump instance to attempt to probe
hardware already owned by the primary disk driver, leading to a system-wide
deadlock.
To reproduce:
stat /dev/rumpdiskusb
(rump starts again ... deadlock)
With this patch:
stat /dev/rumpdiskusb
(normal printout of stats, no deadlock)
