xenbus: don't look up transaction IDs for ordinary writes
[ Upstream commit 9a035a40f7f3f6708b79224b86c5777a3334f7ea ]
This should really only be done for XS_TRANSACTION_END messages, or
else at least some of the xenstore-* tools don't work anymore.
Fixes: 0beef634b8 ("xenbus: don't BUG() on user mode induced condition")
