xfs: fix duplicate includes

Header files were already included, just not in the normal order.
Remove the duplicates, preserving normal order. Also move xfs_ag.h
include to before the scrub internal includes which are normally
last in the include list.

Fixes: d5c88131dbf0 ("xfs: allow queued AG intents to drain before scrubbing")
