LU-6635 lfsck: block replacing the OST-object for test

For sanity-lfsck test_18e, sometimes, before the client wirte
happened, the layout LFSCK has already gone into the phase2
and replaced the new created OST-object with the old orphan
OST-object, then cause the subsequent check failure.

To resolve such trouble, we will hold the layout LFSCK when
replacing the new created OST-object until the client write
happened.
