Move the code for freeingn a TMF from qla_target.c into tcm_qla2xxx.c. This allows to remove the free_mcmd function pointer from struct qla_tgt_func_tmpl. Since tcm_qla2xxx_queue_tm_rsp() is called from thread context, call transport_generic_free_cmd() directly instead of queueing another work item.
