gpu: nvgpu: cleanup allocator debugging

Browse Source 
Remove debugging features that did not really get used and make
the debugging code use the nvgpu_log() functionality. This ties
the allocator debugging into the larger nvgpu debug framework.

Also modify many of the places CONFIG_DEBUG_FS was used to
conditionally compile allocator debug code to use __KERNEL__
instead. This is because that debug code can still be called even
when debugfs is not present in Linux.
