staging: r8822be: fix null pointer dereference with a null driver_adapter
The call to _rtl_dbg_trace via macro HALMAC_RT_TRACE will trigger a null pointer deference on the null driver_adapter. Fix this by assigning driver_adapter earlier to halmac_adapter->driver_adapter before the tracing call so that a non-null driver_adapter is passed instead.
