gpu: nvgpu: add check for "vm->num_user_mapped_buffers"
The "nvgpu_big_zalloc()" will be failed if the passed-in argument
"vm->num_user_mapped_buffers" is zero. The returned value is 16
which will bypass the NULL-check and then causes the panic.
This patch adds a check on the "vm->num_user_mapped_buffers" to
avoid the zero is passed-in the "nvgpu_big_zalloc()".
