[PATCH v2 02/14] shared/gatt-db: Pass the ATT opcode to the notify callback

[Cheng Jiang <cheng.jiang@oss.qualcomm.com>]

gatt_db_read_t and gatt_db_write_t both tell the callback which ATT
operation it is serving through an opcode argument. gatt_db_notify_t does
not, so a notify callback can only assume a notification.

Pass the opcode the same way, set to BT_ATT_OP_HANDLE_NFY, which is what
gatt_db_attribute_notify() has always meant. No caller behaviour changes
yet; it gives the callback somewhere to read the transport from once there
is more than one.
