Make cmd_ring_size changeable similar to the way it is done for
max_data_area_mb. The reason is that our tcmu client will create thousands
of tcmu instances, and this will consume lots of mem with default 8Mb cmd
ring size for every backstore.

One can change the value by typing:

    echo "cmd_ring_size_mb=N" > control

The "N" is a integer between 1 to 8, if set 1, the cmd ring can hold about
6k cmds(tcmu_cmd_entry about 176 byte) at least.

The value is printed when doing:

    cat info

In addition, a new readonly attribute 'cmd_ring_size_mb' returns the value
in read.

Instead of storing the iSCSI task pointer and the session age in the SCSI
pointer, use command-private variables. This patch prepares for removal of
the SCSI pointer from struct scsi_cmnd.

The list of iSCSI drivers has been obtained as follows:
$ git grep -lw iscsi_host_alloc
drivers/infiniband/ulp/iser/iscsi_iser.c
drivers/scsi/be2iscsi/be_main.c
drivers/scsi/bnx2i/bnx2i_iscsi.c

drivers/scsi/iscsi_tcp.c
drivers/scsi/libiscsi.c
drivers/scsi/qedi/qedi_main.c
drivers/scsi/qla4xxx/ql4_os.c
include/scsi/libiscsi.h

Note: it is not clear to me how the qla4xxx driver can work without this
patch since it uses the scsi_cmnd::SCp.ptr member for two different
purposes:
- The qla4xxx driver uses this member to store a struct srb pointer.
- libiscsi uses this member to store a struct iscsi_task pointer.
