f03ee50232 gpu: nvgpu: gp10b: only create ECC stats once 
The ECC sysfs stat creation function is called on GR init. GR can get
initialized multiple times but we only need to create the ECC stats
once. Therefore, add a check to avoid creating duplicate stat sysfs
nodes.

63d463c1ac gpu: nvgpu: gp10b: make local symbol static 
Fixed the following sparse warning by making local symbol static:
- platform_gp10b_tegra.c:365: warning: symbol 'ecc_hash_table' was not declared.
                                       Should it be static?
