Fixed display filters for 50D

For display filters on the 50D, a change to state-object.c
appears to have been missed in an earlier backport from TL: calling display_filter_lv_vsync()
on the lvVdInterrupt
state transition. For reference, here is the TL commit and the earlier backport.
This fixes flickering with ML grayscale preview, anamorphic, and so forth. However, I may have missed a reason why this change was not backported.
