staging: r8822be: fix null pointer dereferences with a null driver_adapter
The call to _rtl_dbg_trace via macro HALMAC_RT_TRACE will trigger a null pointer deference on a 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. I should have spotted these with an earlier patch I sent, but I overlooked these in the rather large CoverityScan logs.
