[libvirt] [PATCH 6/7] xend_internal.c: assure clang that we do not dereference NULL

[Jim Meyering <jim@xxxxxxxxxxxx>]

From: Jim Meyering <meyering@xxxxxxxxxx>

* src/xen/xend_internal.c (xend_parse_sexp_desc_char): Add three
uses of sa_assert, each preceding a strchr(value,... to assure
clang that "value" is non-NULL.
