pageinspect: Fix unaligned struct access in GIN functions
The raw page data that is passed into the functions will not be aligned
at 8-byte boundaries. Casting that to a struct and accessing int64
fields will result in unaligned access. On most platforms, you get away
with it, but it will result on a crash on pickier platforms such as ia64
and sparc64.
