device: Don't browse SDP if HIDSDPDisable is set
According to the HID1.1 spec, part 5.3.4.9:
The HIDSDPDisable attribute is a Boolean value, which indicates
whether connection to the SDP channel and Control or Interrupt
channels are mutually exclusive. This feature supports Bluetooth
HID devices that have minimal resources, and multiplex those
resources between servicing the initialization (SDP) and runtime
(Control and Interrupt) channels.
However, Bluez still tries to connect SDP upon HID connection,
regardless of the existence of the HIDSDPDisable attribute.
This patch prevents the connection of SDP after HID has been
established, if the device has HIDSDPDisable attribute.
