[PATCH] unit/test-gatt: Fix hung issue

[<mingli.yu@windriver.com>]

From: Mingli Yu <mingli.yu@windriver.com>

The below test hangs infinitely
$ unit/test-gatt -p  /robustness/unkown-request -d
/robustness/unkown-request - init
/robustness/unkown-request - setup
/robustness/unkown-request - setup complete
/robustness/unkown-request - run
  GATT: < 02 17 00                                         ...
  bt_gatt_server:MTU exchange complete, with MTU: 23
  GATT: > 03 00 02                                         ...
  PDU: = 03 00 02                                         ...
  GATT: < bf 00

Actually, the /robustness/unkown-request test does
no action.
