[2/1] xfs: fix xfs_error_get_cfg for negative errnos

Commit Message

Fix up a couple places where flag manipulation is unclear.

In the first case we clear XBF_ASYNC and then immediately
reset it.

In the 2nd case we are at a point in the function where the
buffer must already be async, so no need to reset it.

Add consistent spacing around the " | " while we're at it.
