Nitin Kumbhar 13cc7ea93d gpu: nvgpu: mask intr before gpu power off 
once gpu is powered off i.e. power_on set to false, nvgpu isr
does not handle stall/nonstall irq. Depending upon state
of gpu, this can result in either of following errors:

1) irq 458: nobody cared (try booting with the "irqpoll" option)
2) "HSM ERROR 42, GPU" from SCE if it detects that an interrupt is
not in time.

Fix these by masking all interrupts just before gpu power off
as nvgpu won't be handling any irq anymore.

While masking interrupts, if there are any pending interrupts,
then report those with a log message.
