gpu: nvgpu: defer channel worker initialization
kthread_run can fail if SIGKILL is triggered on an application during
driver load.
On this change we defer the channel worker init to the enqueue to avoid
this condition during driver power on which would cause the driver state to be
corrupted leaving subsequent attempts to load the driver unsuccesful.
By moving this code to a later time, it is now needed to protect the task
structure with a mutex.
