OMAPDSS: APPLY: fix NULL pointer deref when mgr is not set

Browse source 
extra_info_update_ongoing() goes through all overlays, but doesn't check
if the overlay is connected to a manager. This leads to a crash whenever
an overlay has been detached.

Add a check to skip the non-connected overlays.
