DF-5322 fix validation (fix.diff applied to the guest's /usr/src copy,
module rebuilt against the PATCHED production firewire.c, identical
trigger)

$ cd /usr/src && patch -p1 < /root/df5322/fix.diff
   PATCHED (10 hunks firewire.c + 1 hunk firewirereg.h)
$ sh /root/df5322/build.sh        (fix_build.log)
$ kldload /root/df5322/df5322.ko
$ sysctl kern.df5321_mode=0 kern.df5321_iters=5000
$ sysctl kern.df5321_fire=1

DF5322: 5000 split-transaction timeouts
DF5322: M_FW inuse delta = 0 objects, memuse delta = 0 bytes (each leaked struct tlabel = 16 bytes)
DF5322: no significant leak (fixed kernel?)

FIX STATUS: fixed  (baseline: 5000 objects / 80000 bytes)
