spa: libcamera: source: remove format config shortcut

Browse source 
Remove the code that is supposed to compare the current and the to-be-set
format for returning early if they match. This is removed:

  * v4l2 also does not have it either;
  * it needs more consideration (there are not properly handled fields);
  * it would make later changes somewhat more complicated.
