[PATCH v3 4/4] migration: Expose 'cancelling' status to user

[zhanghailiang <zhang.zhanghailiang@xxxxxxxxxx>]

'cancelling' status is introduced by commit 51cf4c1a, which is mainly avoid
possible starting a new migration process while the previous one still exist.
But we don't expose this status to user, instead by return a 'active' state.

Here, we expose it to the user (such as libvirt), 'cancelling' status only
occurs for a short window before the migration aborts, so for users,
if they cancell a migration process, it will observe 'cancelling' status
occasionally.
