This fixes a bug found by Lv Yunlong where because beiscsi_exec_nemb_cmd frees memory for the be_dma_mem cmd, we can access freed memory when beiscsi_if_clr_ip/beiscsi_if_set_ip's call to beiscsi_exec_nemb_cmd fails and we access the freed req. This fixes the issue by having the caller free the cmd's memory.
Applied to 5.15/scsi-queue, thanks!
