[XFS] Remove unused arguments from the XFS_BTREE_*_ADDR macros.
It makes it incrementally clearer to read the code when the top of a macro
spaghetti-pile only receives the 3 arguments it uses, rather than 2 extra
ones which are not used. Also when you start pulling this thread out of
the sweater (i.e. remove unused args from XFS_BTREE_*_ADDR), a couple
other third arms etc fall off too. If they're not used in the macro, then
they sometimes don't need to be passed to the function calling the macro
either, etc....
