compiler: fix warning with GCC 4.8.0
GCC 4.8.0 introduces a new warning: block/qcow2-snapshot.c: In function 'qcow2_write_snapshots’: block/qcow2-snapshot.c:252:18: error: typedef 'qemu_build_bug_on__253' locally defined but not used [-Werror=unused-local-typedefs] QEMU_BUILD_BUG_ON(offsetof(QCowHeader, snapshots_offset) != ^ cc1: all warnings being treated as errors (Caret diagnostics aren't perfect yet with macros... :)) Work around it with __attribute__((unused)).
