[bug report] most of blktests nvme/ failed on the latest linux tree

[Yi Zhang]

Hello

I found this failure on the latest linux tree, and it cannot be
reproduced on v6.4,
it should be one regression recently merged to linux tree after v6.4.
I check the commit recently merged after v6.4, and found below commit
touched the related code, not sure if it was introduced by this
commit.
