The routine used by the SDMA cache to handle already cached nodes can extend an already existing node. In its error handling code, the routine will unpin pages when not all pages of the buffer extension were pinned. There was a bug in that part of the routine, which would mistakenly unpin pages from the original set rather than the newly pinned pages. This commit fixes that bug by offsetting the page array to the proper place pointing at the beginning of the newly pinned pages.
