gpu: nvgpu: fix resource leak

We pass (struct device_attribute *) to gp10b_ecc_stat_create()
and gr_gp10b_ecc_stat_create() and then assign a memory
allocation to this pointer
But since this pointer is local copy to function, static
pointer variables are never set in gr_gp10b_create_sysfs()

This also results in a resource leak since we never free
the storage assigned to local variable

Fix this by adding correct parameter (struct device_attribute **)
so that the address of the allocation is returned to the caller
correctly
