Log Message:
-----------
In ReadOrZeroBuffer (and related entry points), don't bother to call
PageHeaderIsValid when we zero the buffer instead of reading the page in.
The actual performance improvement is probably marginal since this function
isn't very heavily used, but a cycle saved is a cycle earned.
