gpu: nvgpu: fix erroneous gk20a_put() call
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()
