LU-7342 test: test_85a: unused locks error

When we changed FSNAME from lustre to lustre-1, $3
will give “addr” value “clilov” instead of getting
proper address, due to this we are getting "Found no match" error.
But if we change $3 to $NF getting addr value correctly.
Generally NF will give total number of fields in the current
input, but in our case it happens to be last field.
