gpu: nvgpu: move cycle state buffer handler to linux

Browse Source 
We use dma_buf pointer cyclestate_buffer_handler in common code
But since this is linux specific, we need to move this out of common code and
into linux specific code

Move dma_buf pointer cyclestate_buffer_handler from common channel code to
struct nvgpu_channel_linux

Fix all pointer accesses to this handle

Move gk20a_channel_free_cycle_stats_buffer() to ioctl_channel.c since it is
mostly linux specific
And since gk20a_channel_free_cycle_stats_buffer() needs to be called while
closing the channel, call it from nvgpu_channel_close_linux()
