Peter Maydell d4aceb2eb7 hw/display/qxl.c: Use trace_event_get_state_backends()
The preferred way to test whether a trace event is enabled is to
use trace_event_get_state_backends(), because this will give the
correct answer (allowing expensive computations to be skipped)
whether the trace event is compile-time or run-time disabled.
Convert the old-style direct use of TRACE_FOO_ENABLED.
