disp: msm: add feature-enabled check for output hw-fence sw-override

In the case that the hw-fence feature is enabled in the display driver dt
but disabled during initialization by the display driver when hw-fence
driver dependency is disabled, the existing check to determine
if the function pointer is available is not sufficient to determine
if the feature is enabled. This change adds an additional check to ensure
we do not set the output-fences sw-override unless hw-fencing is enabled.
