[ Upstream commit 0e98c084a21177ef136149c6a293b3d1eb33ff92 ]
Commit fb7c02445c49 ("ext4: pass -ESHUTDOWN code to jbd2 layer") want to allow jbd2 layer to distinguish shutdown journal abort from other error cases. So the ESHUTDOWN should be taken precedence over any other errno which has already been recoded after EXT4_FLAGS_SHUTDOWN is set, but it only update errno in the journal suoerblock now if the old errno is 0.
