drm/i915/vrr: Use set_context_latency instead of intel_vrr_real_vblank_delay()

Browse Source 
The helper intel_vrr_real_vblank_delay() was added to account for the
SCL lines for TGL where we do not have the TRANS_SET_CONTEXT_LATENCY.

Now, since we already are tracking the SCL with new member
`set_context_latency` use it directly instead of the helper.
