[Xen-devel] [PATCH] xl: allow nameless domains to be named

At present, find_domain() will exit(2) if you specify a domain by
number, but that domain doesn't have a corresponding name.  However,
nothing seem to critically depend on common_domname being set, and the
test prevents dom0 or other nameless domains from being named.  So just
remove the check.
