gpu: nvgpu: update ecc sysfs node handling

Browse Source 
Make ecc sysfs hash table per GPU by adding it as
part of nvgpu_os_linux. Using a single hash table
might give incorrect results as GPUs have same filenames
and a filename is used as a key for a lookup.

Add device_attribute as part of struct gk20a_ecc_stat. Using
a single array of pointers of device attribute for an
ecc_stat results in memory leak and incorrect stats if
multiple GPUs are present on the system. This array of pointers
will always hold info for GPU which created sysfs nodes last.
Fix this by making device attribute array per ecc stat per GPU.

Fix ecc stat removal to consider zero sub-units for a given
number of hwunits. The multiplication with zero results
in not removing any sysfs node at all.
