media: saa6752hs: Don't set format in sub-device state

For the purpose of setting old non-pad based sub-device try format as a
basis for VIDIOC_TRY_FMT implementation, there is no need to set the
format in the sub-device state. Drop the assignment to the state, which
would result in a NULL pointer dereference.
