gpu: nvgpu: pg init task hogging cpu
The Pg init task hogs the kernel by having a wait condition with no timeout
waiting for pg state change, but ps state may not post a change in a long time
depending on runtime conditions, so we get soft-crashes warning spews in the
kernel
We solve this by making the condition wait interruptible
