block/qcow2-cluster: Add missing "fallthrough" annotation
When compiling with -Werror=implicit-fallthrough, the compiler currently complains: ../../devel/qemu/block/qcow2-cluster.c: In function ‘cluster_needs_new_alloc’: ../../devel/qemu/block/qcow2-cluster.c:1320:12: error: this statement may fall through [-Werror=implicit-fallthrough=] if (l2_entry & QCOW_OFLAG_COPIED) { ^ ../../devel/qemu/block/qcow2-cluster.c:1323:5: note: here case QCOW2_CLUSTER_UNALLOCATED: ^~~~ It's quite obvious that the fallthrough is intended here, so let's add a comment to silence the compiler warning.
