Bo Chen 8fd8224ee3 vmm: Use HashSet for VmConfig::preserved_fds
Each VM reboot re-entered the VFIO/virtio-net add paths and re-appended
the same originating fds, leaving duplicates in preserved_fds and a
double-close hazard at final teardown. Switching to HashSet makes
add_preserved_fds idempotent.
