msm: kgsl: Don't wait for context that has not submitted
A context may be detached without submitting any commands
to GPU ringbuffer. This may cause us to wait on a timestamp
that will never be retired. So return immediately from
adreno_drawctxt_wait_rb() if context has not submitted any
commands to GPU ringbuffer.
