ORIGIN_CURSOR_UPDATE falls through to _psr_flush_handle() on LNL
(DISPLAY_VER >= 20), which calls intel_psr_exit(). Cursor plane updated
via legacy ioctl (drmModeMoveCursor) does not dirty the primary
frontbuffer, no PSR2 state change is needed. Match the existing
ORIGIN_FLIP behavior by unconditionally returning early.
Before this, the psr2_sel_fetch_enabled guard only prevented the early
return when PSR2 selective fetch was active, sending cursor updates
through intel_psr_exit() and causing a black line artifact on some
panels during the exit/re-enable transition.
Fixes: ef39826c12b4 ("drm/i915/display: Fix glitches when moving cursor with
PSR2 selective fetch enabled")
