xmem/tmem: fix 'undefined variable' build error.
In the (not so useful) kernel configuration where CONFIG_SWAP is undefined and CONFIG_XEN_SELFBALLOONING is defined, xen_tmem_init would use undefined variable 'static bool frontswap'. Added #else to have #define frontswap (0) in the case where CONFIG_FRONTSWAP is not defined.
