android: camera_device: Use reference to settings

In preparation to use the keys part of a capture request to
fill in the result metadata, create a reference to
descriptor_->settings_.

While at it, move the 'ret' variable declaration to the beginning of
the function and rename it in 'found', as it will be used in many
places and move the \todo comment up as it applies to all metadata
whose value is copied from settings.
