LU-11111 lfsck: print correct parent FID

LU-11111 lfsck: print correct parent FID

The LFSCK debug message for repairing a striped directory incorrectly
prints the child FID twice, rather than printing the parent FID:

  MDT0002-osd: namespace repair shard 0 [0x68002f9d1:0xa47c:0x0] ...
           ... of the striped directory [0x68002f9d1:0xa47c:0x0]

Fix this to print the parent FID.
