target: Remove core TRANSPORT_FREE_CMD_INTR usage
This patch drops TRANSPORT_FREE_CMD_INTR usage from target core, which includes the removal of transport_generic_free_cmd_intr() symbol, TRANSPORT_FREE_CMD_INTR usage in transport_processing_thread(), and special case LUN_RESET handling to skip TRANSPORT_FREE_CMD_INTR processing in core_tmr_drain_cmd_list(). We now expect that fabric modules will use an internal workqueue to provide process context when releasing se_cmd descriptor resources via transport_generic_free_cmd().
