largefiles: avoid printing messages while transplanting by "_lfstatuswriters"

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

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