[PATCH BlueZ 1/2] gatt-api: Add error code ReadValue/WriteValue

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

This allows application to return error codes in the range allowed by
the spec:

 'GATT - Section 4.9.5:

  Application Error 0x80 – 0x9F Application error code defined by a
  higher layer specification.'
