msm: kgsl: Check if GPU is hung when reserving space in rb
A busy loop is executed when we allocate space from the ringbuffer.
If the GPU is hung then we can wait indefinitely in the busy loop.
Add a wait time to this busy loop, and if the wait time elapses then
report a GPU hang instead of waiting indefinitely.
