[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
