Camera: Removing cachedump call to miminimize delay during close.

- The cacheDump() call was added for better debugging by always
  dumping the state of the last camera session. Since LT/VT chipsets
  it is adding significant delay during camera close. Hence we are
  removing cachedump call during disconnect.
