Fix failure when a shared tidbitmap has only one page.
Commit 98e6e89040a0534ca26914c66cae9dd49ef62ad9 made inadequate
provision for the case of a single-page shared tidbitmap. It
allocate space for a shared PagetableEntry, but failed to
initialize it.
Report by Thomas Munro. Patch by Dilip Kumar, with some comment
changes by me.
