largefiles: avoid printing messages while rebasing by "_lfstatuswriters"

Putting "lambda *msg, **opts: None" (= avoid printing messages always)
into "_lfstatuswriters" while rebasing makes explicit passing
"printmessage = False" for "updatelfiles()" useless.

This patch also removes setting/unsetting "repo._isrebasing" in
"overriderebase", because there is no code path referring it.
