drm/amd/display: handle nulled pipe context in DCE110's set_drr()
As set_drr() is called from IRQ context, it can happen that the
pipe context has been nulled by dc_state_destruct().
Apply the same protection here that is already present for
dcn35_set_drr() and dcn10_set_drr(). I.e. fetch the tg pointer
first (to avoid a race with dc_state_destruct()), and then
check the local copy before using it.
Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/3142
Fixes: 06ad7e164256 ("drm/amd/display: Destroy DC context while keeping DML and DML2")
