gpu: nvgpu: do not disable fb hub intr in fault info mem destroy

Browse Source 
FB hub intr is enabled on finzalize_poweron and disabled on
prepare_poweroff. There is no need to additionally disable
FB hub intr in fault info mem destroy when driver refcount
becomes zero since prepare_poweroff has already been called.
Also prepare_poweroff locks GPU registers from CPU access so
these registers should not be accessed after prepare_poweroff.
