gpu: nvgpu: move snapshot_client memory handling to linux
We right now store dmabuf fd and dma_buf pointer for gk20a_cs_snapshot_client
But since dma_buf and all related APIs are linux specific, we need to remove
them from common code and move them to linux specific code
Add new linux specific structure gk20a_cs_snapshot_client_linux which includes
struct gk20a_cs_snapshot_client and linux specific dma_buf pointer
In gk20a_attach_cycle_stats_snapshot(), we first handle all dma_buf related
operations and then call gr_gk20a_css_attach()
Move gk20a_channel_free_cycle_stats_snapshot() to ioctl_channel.c
In gk20a_channel_free_cycle_stats_snapshot(), we call gr_gk20a_css_detach()
and then free up dma_buf in linux specific code
We also need to call gk20a_channel_free_cycle_stats_snapshot() while closing
the channel, so call it from linux specific nvgpu_channel_close_linux()
