[ofw] issue with checkin# 3122

[Uri Habusha]

Hi Stan,

I adopted your checkin# 3122 - IOC poll on demand.

When disabling the drive an ASSERT is popup. The ASSERT is in  following code in port_mgr_pnp_cb function

                                CL_ASSERT( p_ctx );    <== The problematic assert
                                if (p_ctx)
                                {
                                                p_bfi = p_ctx->p_bus_filter;
                                                CL_ASSERT( p_bfi );
                                                if (p_bfi->p_port_mgr->active_ports > 0)
                                                                cl_atomic_dec( &p_bfi->p_port_mgr->active_ports );
                                }
                                port_mgr_port_remove( (ib_pnp_port_rec_t*)p_pnp_rec );
                                break;

I noticed that in the port_mgr_port_remove there is a check if the ctx is valid or not. So I guess it's a known issue that can happen. For now I removed the assert in our code.

Please take a look in the code and see if it's valid fix (if so please change ofw code accordingly) or debug the issue. It happens when disable \enable the low level driver.
