largefiles: remove useless overrideupdate

Now, "overrideupdate()" wrapping "hg update" is useless, because
"workingctx.dirty() and raising Abort" in "hg update" was replaced by
"cmdutil.bailifchanged()" in the previous patch, and the latter can
detect changes of largefiles in the working directory.
