[Request] [+ ] D12203: scmutil: revert c7e675848027 / scmutil: obsrevs is already a frozenset

REVISION SUMMARY
  The reverted change breaks nearly every command for me when I'm using
  obsolescence. Specifically, I get `TypeError: unhashable type: 'set'`
  on the changed line. The deleted comment actual draws attention to this
  issue.

REPOSITORY
  rHG Mercurial

BRANCH
  stable
