Subject: [PATCH v10 05/17] Update BitmapAdjustPrefetchIterator parameter type
 to BlockNumber

BitmapAdjustPrefetchIterator() only used the blockno member of the
passed in TBMIterateResult to ensure that the prefetch iterator and
regular iterator stay in sync. Pass it the BlockNumber only. This will
allow us to move away from using the TBMIterateResult outside of table
AM specific code.
