v2: Don't leak blk->vmsh when BB is deleted before the callback is called.
[Stefan]
From stub functions, don't return g_malloc0(1) which is risky, return NULL.
[Eric]
"nbd-server-add -w" doesn't work when we are in "-incoming defer" state:
(qemu) nbd_server_add -w drive-virtio-disk0
Block node is read-only
Two problems are faced:
- nbd_export_new() calls bdrv_invalidate_cache() too late.
- bdrv_invalidate_cache() restores qdev permission (which are temporarily
masked by BlockBackend.disable_perm during INMIGRATE) too early.
Fix both, and add a regression iotest.

stubs: Add vm state change handler stubs
block-backend: Defer shared_perm tightening migration completion
iotests: Add non-shared storage migration case 192

nbd: Fix order of bdrv_set_perm and bdrv_invalidate_cache
