gpu: nvgpu: return ENOSPC if no private command buffer space

If we run out of gpfifo space or private command
buffer space, we currently return EAGAIN as error code

Instead of EAGAIN, return ENOSPC as error code so
that caller (user space) can read the error code
and do some re-trials

As the jobs are processed, it is possible to free up
some space. And hence such re-trials could succeed
