Description Xiubo Li 2023-07-20 09:04:19 UTC 
If just before the revoke request, which will increase the 'seq', is
sent out the clients released the corresponding caps and sent out
the cap update request with old 'seq', the mds will miss checking
the seqs and calculating the caps.

We should always send an ack for revoke requests.
