Bluetooth: Mesh: Fix GATT Proxy & Node Identity state binding
Bluetooth: Mesh: Fix GATT Proxy & Node Identity state binding

Section 4.2.11.1 of the Mesh Profile specification 1.0 states:

"When the GATT Proxy state is set to 0x00, the Node Identity state for
all subnets shall be set to 0x00 and shall not be changed."

When the proxy state has been changed we also need to wake up the
advertising module to make sure we do the right kind of advertising.
