  device: fix inverted NULL check in gatt_db clone

gatt_db_clone() returns NULL on failure so the condition was inverted.
With the old check a successful clone (non-NULL) would return false and
skip swapping the device's GATT database, while a failure (NULL) would
fall through and dereference a NULL pointer a few lines below.

Fix by negating the condition: only bail out early if the clone failed;
proceed with the swap when the clone actually succeeds.
