drh 42e28f12a3 Simplify the accessPayload() routine so that it always populates the overflow
page cache.  In the one case where populating the page cache can lead to 
problems, simply invalidate the cache as soon as accessPayload() returns.  
This simplification reduces code size and helps accessPayload() to run a 
little faster.  This backs out the eOp==2 mode of accessPayload() added by 
check-in [da59198505].
