dagop: minor python optimization to `headrevs`

Less lookup and less function call never hurt. This provides a small speedup
on various run of the 'heads()' revset. This also buys back some of the slow
down we observed in the previous changesets for single value lookup.

Performance number:
0) before dagop.headrevs usage
1) after dagop.headrevs usage
2) after this change
