drm/omap: fix NULL but dereferenced coccicheck error

Browse Source 
Fix the following coccicheck warning:
./drivers/gpu/drm/omapdrm/omap_overlay.c:89:22-25: ERROR: r_ovl is NULL
but dereferenced.

Here should be ovl->idx rather than r_ovl->idx.

Fixes: e02b5cc9e8 ("drm/omap: Add a 'right overlay' to plane state")
