Nitin Kumbhar 7882f15ff6 gpu: nvgpu: fix possible buffer overflow issue ...

As sprintf() is used to populate pool_name[20], it can overflow
for larger u32 values (u32 max decimal number chars are 10) i.e.
20 < strlen("semaphore_pool-") i.e. 15 + 10.

Fix this overflow by removing pool_name as it's not used.
