subrepo: drop the 'ui' parameter to revert()

This no longer needs to be explicitly passed because the subrepo object tracks
the 'ui' reference since fcbc66b5da6a.  See the change to 'archive' for details
about the differences between the output level in the root repo and subrepo 'ui'
object.

The only use for 'ui' in revert is to emit status and warning messages, and to
check the verbose flag prior to printing the action to be performed on a file.

The local repo's ui was already being used to print a warning message in
wctx.forget() and for 'ui.slash' when walking dirstate in the repo.status()
call.  Unlike other methods where the matcher is passed along and narrowed, a
new matcher is created in each repo, and therefore the bad() method already used
the local repo's ui.
