drm/omap: fix crash if state->fb is NULL
Commit 5dd9a556bd46e0074132a49b3e5758c908fb1556 ("drm/omap: dynamically
assign hw overlays to planes") changed omap_plane_atomic_check() so that
the function no longer returns 0 at the very beginning if state->fb ==
NULL. This causes a crash when rotation is used and we call
omap_framebuffer_supports_rotation(state->fb).
Fix this by moving the rotation check inside if (state->visible) block.
