Michal Privoznik e0392f5a74 xen: Check return value of virStringReplace
After 6604a3dd9f8 in which new helper function has been
introduced, the code calls virStringReplace and dereference the
result immediately. The string function can, however, return NULL
so this would SIGSEGV right away. Check for the return value of
the string function.
