Remove unneeded casts of BufferGetPage() result

Browse Source 
BufferGetPage() already returns type Page, so casting it to Page
doesn't achieve anything.  A sizable number of call sites does this
casting; remove that.

This was already done inconsistently in the code in the first import
in 1996 (but didn't exist in the pre-1995 code), and it was then
apparently just copied around.
