Use cmds_max passed from user space to be the number of PDUs to be supported for the session instead of hard-coded ISCSI_DEF_XMIT_CMDS_MAX. This allow controlling the max number of SCSI commands for the session. Also don't ignore the qdepth passed from user space. Derive from session->cmds_max the actual number of RX buffers and FMR pool size to allocate during the connection bind phase. Since the iser transport connection is established before the iscsi session/connection are created and bound, we still use one hard-coded quantity ISER_DEF_XMIT_CMDS_MAX to compute the maximum number of work-requests to be supported by the RC QP used for the connection. The above quantity is made to be a power of two between ISCSI_TOTAL_CMDS_MIN (16) and ISER_DEF_XMIT_CMDS_MAX (512) inclusive.
