cnic: Fix context memory init. on 5709.

We need to zero context memory on 5709 in the function cnic_init_context().
Without this, iscsid restart on 5709 will not work because of stale data.
TX context blocks should not be initialized by cnic_init_context() because
of the special remapping on 5709.

Update version to 2.1.2.
