cnic: Do not call bnx2i when bnx2i is calling cnic_unregister_driver()

Browse Source 
We should call bnx2i to send the iSCSI netlink message earlier in
cnic_unregister_device().  By the time cnic_unregister_driver() is
called, bnx2i may have freed data structures used by the upcalls.

Update version to 2.2.12.
