For historical reasons these do not use sizeof, and Coverity caught a mistake in EVT_ENCRYPT_CHANGE_SIZE. In addition: - remove create_conn_cancel_cp, which is unused and doesn't match the kernel and BlueZ's struct definition; - remove read_link_quality_cp altogether; it's off by two, BlueZ doesn't know about it and it seems like a wrong copy of read_link_policy_cp; - fix inquiry_info which is shorter by one: the kernel has a struct that is 14 byte long, but not counting the initial num_responses byte which the kernel parses separately; - remove extended_inquiry_info altogether, since it's not used and unlike the other inquiry structs does not have the initial num_responses byte.
