With a recent rework we moved gk20a_get() call to nvgpu_ioctl_tsg_open(),
but corresponding gk20a_put() call remained in gk20a_tsg_release()
So if a TSG is opened and released from within kernel with APIs
gk20a_tsg_open()/gk20a_tsg_release() we mistakenly drop extra refcount
through gk20a_put()
Fix this by moving gk20a_put() call to nvgpu_ioctl_tsg_release() which
balances gk20a_get() call in nvgpu_ioctl_tsg_open()

All the event ids NVGPU_IOCTL_CHANNEL_EVENT_ID_* are defined in linux
specific user header uapi/linux/nvgpu.h and can't be used in common
code
Hence add new definitions of type NVGPU_EVENT_ID_* for all the events

For future additions to event ids, we need to update both
NVGPU_IOCTL_CHANNEL_EVENT_ID_* and NVGPU_EVENT_ID_* fields
Also add new API nvgpu_event_id_to_ioctl_channel_event_id() to convert
common event_id of the form NVGPU_EVENT_ID_* to Linux specific event_id
of the form NVGPU_IOCTL_CHANNEL_EVENT_ID_*

Fix a race condition in gk20a_get_channel_from_file() that returns a
channel pointer from an fd: take a reference to the channel before
putting the file ref back. Now the caller is responsible of releasing
the channel reference eventually.
Also document why dbg_session_channel_data has to hold a ref to the
channel file instead of just the channel: that might deadlock if the fds
were closed in "wrong" order.
