From: Maurizio Lombardi <mlombard@xxxxxxxxxx> [ Upstream commit af21250bb503a02e705b461886321e394b300524 ] If a reset controller is executed while the initiator is performing some I/O the driver may leak the memory allocated for the commands' iovec. Make sure that nvmet_tcp_uninit_data_in_cmds() releases all the memory.
