libcamera: controls: Fix `ControlInfoMap::count(unsigned int)`

The two overloads of `find()` and `at()` have the same behaviour
regardless of the argument type: `unsigned int` or `const ControlId *`.
However, `count()` is not so because `count(unsigned int)` only checks
the `ControlIdMap`, and it does not check if the given id is actually
present in the map storing the `ControlInfo` objects.

So `count()` returns 1 for every control id that is present in the
associated `ControlIdMap` regardless of whether there is an actual
entry for the `ControlId` associated with the given numeric id.

Fix that by simply using `find()` to determine the return value.
