gpu: nvgpu: Fix kmem debugging

Browse Source 
Make the kmem debugging prints much more easily usable. Previously the
prints would only take effect if the full tracking was enabled:

  CONFIG_NVGPU_TRACK_MEM_USAGE

However, there are many times when just the debug prints would be nice
to have by simply setting the log mask bit in the log mask.

  echo 0x80000 > /sys/kernel/debug/<gpu>/log_mask

Also this change now uses the real nvgpu_log() function instead of the
legacy nvgpu_dbg() function. This makes the logging appear with proper
GPU printing as well.
