Xiaoli Feng ce96e888fe Fix nfs4.2 return -EINVAL when do dedupe operation 
dedupe_file_range operations is combiled into remap_file_range.
But in nfs42_remap_file_range, it's skiped for dedupe operations.
Before this patch:
  # dd if=/dev/zero of=nfs/file bs=1M count=1
  # xfs_io -c "dedupe nfs/file 4k 64k 4k" nfs/file
  XFS_IOC_FILE_EXTENT_SAME: Invalid argument
After this patch:
  # dd if=/dev/zero of=nfs/file bs=1M count=1
  # xfs_io -c "dedupe nfs/file 4k 64k 4k" nfs/file
  deduped 4096/4096 bytes at offset 65536
  4 KiB, 1 ops; 0.0046 sec (865.988 KiB/sec and 216.4971 ops/sec)
