gpu: nvgpu: Fix gk20a_sync_pt_has_signaled()
Fix a reentrancy problem in gk20a_sync_pt_has_signaled()
where one thread could clear a pointer before another
thread tried to access it. A spinlock was added to the
gk20a_sync_pt struct which is used to ensure that the
underyling gk20a_sync_pt data is accessed in a sane
manner.
