obj: fix pmreorder and two existing failure atomicity bugs

Without this option, the consistency checking function
can mask issues.

This prevented pmreorder tests from failling in certain
scenarios.

This missing drain might have lead to failure atomicity
bug if the store that invalidated the ulog was reordered
by the CPU with any of the log entries and a crash
happened.
