update to the pci_boot.c has caused small memory leak in the
enumerate_bus_devs area on all x86/amd64 systems while testing
nightly ON bits for snv_27, there's 2 putbacks relating to this
file in recent days, ZFS made large change and also a smaller 
targeted fix relating to 1K alignment address allocation. Both
these were made on Oct 31st.
