xfs: simplify the rmap code in xfs_bmse_merge

Source kernel commit: 4cc1ee5e654114aa7fac6993488ad2cd0b3411bb

In Christoph's patch to refactor xfs_bmse_merge, the updated rmap code
does more work than it needs to (because map-extent auto-merges
records).  Remove the unnecessary unmap and save ourselves a deferred
op.
