rebase: use "dirstateguard" instead of "dirstate.invalidate"

Before this patch, "rebase.concludenode" uses "dirstate.invalidate()"
to restore dirstate to original status at failure. But it doesn't work
correctly, if "dirstate.write()" is executed while committing.

This patch uses "dirstateguard" instead of "dirstate.invalidate" to
restore dirstate easily and certainly, even if "dirstate.write()" is

This is the preparation for fixing the issue that recent (in memory)
dirstate isn't visible to external process (e.g. "precommit" hook).

BTW, "cmdutil.duplicatecopies()" invocation on the caller side of
"concludenode()" prevents "dirstateguard" from saving dirstate at the
construction time.

In the future, "duplicatecopies()" invocation should be moved into
"dirstateguard" scope in "concludenode()", and "dirstateguard" should
save dirstate at the construction time for readability.
