block: Add "drained begin/end" for internal snapshot
This ensures the atomicity of the transaction by avoiding processing of
external requests such as those from ioeventfd.
state->bs is assigned right after bdrv_drained_begin. Because it was
used as the flag for deletion or not in abort, now we need a separate
flag - InternalSnapshotState.created.
