F2FS records image errors and checkpoint-stop reasons through the same
s_error_work worker. The ordinary f2fs_handle_error() path only updates
s_errors, but the worker still calls fserror_report_shutdown()
unconditionally after committing the superblock.
As a result, a metadata corruption report can be followed by a synthetic
FAN_FS_ERROR event with ESHUTDOWN and an invalid superblock file handle,
even though no stop reason was recorded.
Track whether save_stop_reason() actually changed the stop_reason array
and only report the shutdown fserror for that case. Pure s_errors updates
still commit the superblock, but no longer generate a false shutdown event.
