  Modified files:
    sys/kern             kern_linker.c 
  Log:
  Fix a bug in the kernel module runtime linker that made it impossible
  to unload the usb.ko module after boot if it was originally preloaded
  from "/boot/loader.conf".  When processing preloaded modules, the
  linker erroneously added self-dependencies the each module's reference
  count.  That prevented usb.ko's reference count from ever going to 0,
  so it could not be unloaded.
