ocfs2: fix reflink preserve cleanup issue

Browse source

[ Upstream commit 5138c936c2 ]

commit c06c303832 ("ocfs2: fix xattr array entry __counted_by error")
doesn't handle all cases and the cleanup job for preserved xattr entries
still has bug:
- the 'last' pointer should be shifted by one unit after cleanup
  an array entry.
- current code logic doesn't cleanup the first entry when xh_count is 1.

Note, commit c06c303832 is also a bug fix for 0fe9b66c65.
