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.
