  Modified files:
    sys/geom             geom_io.c 
  Log:
  When sending request once again because of ENOMEM, reset bio_children
  and bio_inbed fields to 0. Without this change we can end up with
  I/O leakage in some rare situations.
  I tested this change by putting failure probability mechanism simlar
  to this used in NOP class into g_clone_bio(9) function, so it was
  able to return NULL with the given probability.
