xen: netback: use __CONST_RING_SIZE not __RING_SIZE
The later causes warnings with gcc 4.5+. __CONST_RING_SIZE was introduced in
667c78afaec0 to fix this but as netback wasn't upstream at the time it did not
benefit, hence:
CC drivers/net/xen-netback/netback.o
drivers/net/xen-netback/netback.c:110:37: warning: variably modified 'grant_copy_op' at file scope [enabled by default]
drivers/net/xen-netback/netback.c:111:30: warning: variably modified 'meta' at file scope [enabled by default]
drivers/net/xen-netback/netback.c: In function 'xen_netbk_rx_action':
drivers/net/xen-netback/netback.c:584:6: warning: variable 'irq' set but not used [-Wunused-but-set-variable]
Thanks to Witold Baryluk for pointing this out.
