stable inclusion from stable-5.10.50 commit f03d4c12965e1ce454f02572268c9a849fc593b8 bugzilla: 174522 https://gitee.com/openeuler/kernel/issues/I4DNFY

--------------------------------
[ Upstream commit 64bce1ee978491a779eb31098b21c57d4e431d6a ]
When re-connecting, it resets hb_missed_max to 0. Before the first re-connecting, client will trigger re-connection when it gets hb-ack more than 5 times. But after the first re-connecting, clients will do re-connection whenever it does not get hb-ack because hb_missed_max is 0.
There is no need to reset hb_missed_max when re-connecting. hb_missed_max should be kept until closing the session.
