maint: prefer psame_inode, PSAME_INODE, STP_*

Prefer psame_inode, PSAME_INODE, STP_NBLOCKS, and STP_BLKSIZE,
which take addresses of objects, to their counterparts that
take the whole objects.  In some cases the whole objects might
not be initialized, which would be undefined behavior strictly
speaking.
