[PULL 04/12] hw/xen: Fix broken check for invalid state in xs_be_open()

[Anthony PERARD]

From: David Woodhouse <dwmw@amazon.co.uk>

Coverity points out that if (!s && !s->impl) isn't really what we intended
to do here. CID 1508131.

Fixes: 032475127225 ("hw/xen: Add emulated implementation of XenStore 
operations")
