gpu: nvgpu: use nvgpu API to check for allocated memory

Browse Source 
In __gr_gk20a_exec_ctx_ops(), we directly access linux specific pages to check
if memory is allocated or not
Since we need to remove this linux specific dependency from common code,
use common API nvgpu_mem_is_valid() to check if memory is allocated or not
