cnic: Fix locking in init/exit calls.
The slow path ulp_init and ulp_exit calls to the bnx2i driver
are sleepable calls and therefore should not be protected using
rcu_read_lock. Fix it by using mutex and refcount during these
calls. cnic_unregister_driver() will now wait for the refcount
to go to zero before completing the call.
