   Switch some low-hanging fruit to acquire read lock on vmobjects

Could you, please, change the assertion types for object page accessors,
like vm_page_lookup(), as the first step ?

For the out-of-tree code, which is going to be committed later,
this would make life easier.

This is going to happen pretty soon.
Alan and I have some code that depends on such assertions changing and
we want to do it in structured way.
