gpu: nvgpu: Remove init_state initialization code

nvlink core library no longer exposes the set_init_state()
interface as it wishes to block init_state changes from
endpoint drivers.
Now, the core driver is responsible for initializing init_state
variables using set_init_state() interface. Hence, we remove
this redundant code.
