libcamera: media_object: Make MediaLink::setEnabled() account for existing flags
The MediaDevice::setupLink() function fails (ioctl returns EINVAL) when it passes only the MEDIA_LNK_FL_ENABLE flag to a link that is already flagged with MEDIA_LNK_FL_ENABLE and MEDIA_LNK_FL_IMMUTABLE. Contrast to media-ctl's equivalent media_setup_link() which ORs the new flags with the existing values. Fix this by preserving all flags but MEDIA_LNK_FL_ENABLED in MediaLink::setEnabled().
