From: Gopal Tiwari <gtiwari@redhat.com>

While performing the static tool analysis using coverity tool found following reports

Error: RESOURCE_LEAK (CWE-772):
bluez-5.64/client/gatt.c:1531: leaked_storage: Variable "service" going out of scope leaks the storage it points to.

Error: RESOURCE_LEAK (CWE-772):
bluez-5.64/client/gatt.c:2626: leaked_storage: Variable "chrc" going out of scope leaks the storage it points to.

Error: RESOURCE_LEAK (CWE-772):
bluez-5.64/client/gatt.c:2906: leaked_storage: Variable "desc" going out of scope leaks the storage it points to.
