dlm: fixed memory leaks after failed ls_remove_names allocation
commit b982896cdb6e6a6b89d86dfb39df489d9df51e14 upstream.
If allocation fails on last elements of array need to free already
allocated elements.
v2: just move existing out_rsbtbl label to right place
Fixes 789924ba635f ("dlm: fix race between remove and lookup")
