xfs: renumber tests after merge

Tests were merged with high seq numbers to avoid conflicts with
other tests. Now renumber them to contiguous numbers, as all other
tests have been merged correctly. This is easier to do than
assigning the final seq numbers at commit time.

+# FS QA Test No. 346
+#
+# Test fragmentation after writing and dropping CoW extent hint reservation:
+# - Create two reflinked files.  Set extsz hint on second file.
+# - Directio write to random offsets to scatter CoW reservations.
+# - Unmount, remount, repeat (twice more).
+# - Check the number of extents.
