LU-8014 hsm: remove invalid kuc_free in coordinator

Commit 9091a934fc ("LU-8014 hsm: remove kuc_ispayload") moved the KUC
allocation in mdt_hsm_agent_send() and I left a kuc_free in an error
path in mdt_coordinator(). The HAL is no longer a KUC and it is freed
outside the for loop. That kuc_free is incorrect.
