xfs: report the error that made deferred work shut down the fs

Browse source

When a deferred operation fails and shuts the filesystem down,
xfs_defer_finish_noroll() reports neither the errno nor which operation
originated it, so the log cannot tell a transient -ENOSPC from real
corruption.  Report the operation type, errno and remaining reservation.

trace_xfs_defer_finish_error() runs after xfs_force_shutdown(), which
BUGs under fs.xfs.panic_mask and so never fires for the first failure;
move it ahead of the shutdown and mirror it to xfs_alert() for systems
without tracing armed.  Capture the op name while the item is live (dfp
is freed once its work list drains) and suppress the alert once the fs is
already down.
