Subject: scsi: aacraid: fixed IO reporting error
Git-commit: f2244c1b35e5302070af4c729db0b0e9eb8350c9
Patch-mainline: v5.5-rc1
References: jsc#SLE-15152

The problem is the driver detects FastResponse bit set and saves it to
Fib's flags to not check IO response status, but it never clears it for
next IO. Hence the next IO will pick up FastResponse bit to not check
the IO response status and fail to report any type IO error to kernel
