[PATCH] revision.c: fix sparse warnings (sparse algorithm)

Hi Derrick,

If you need to re-roll your 'ds/push-sparse-tree-walk' branch, could
you please squash this into the relevant patch [commit 9949aaeef4
("revision: implement sparse algorithm", 2018-12-14)]. 

This commit caused both 'sparse' and my 'static-check.pl' script to
complain about the visibility of the 'map_flags' variable (it is a
file local variable), so one solution would be to mark it 'static'.
However, it is simply not being used, so ...

Thanks!

ATB,
Ramsay Jones

Thanks, Ramsay! I'm rerolling the series today, so I will make this change.
