See http://permalink.gmane.org/gmane.linux.bluez.kernel/36505. For historical
reasons these do not use sizeof, and Coverity caught a mistake in
EVT_ENCRYPT_CHANGE_SIZE.
In addition:
- remove status from create_conn_cancel_cp; the "status" field is only
in rp structs. Note that this means that the OCF_CREATE_CONN_CANCEL
could never have worked (it would have failed the LENGTH_CHECK), but
I am keeping it anyway.
- 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.
