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")

Confirmed that this patch fixes xenstore-read, xenstore-ls et al, on stable kernel 4.4.17.

It should also go to 4.7, 4.6, 4.1, 3.18.
