drm/omap: silence unititialized variable warning
Smatch complains that "area_free" could be used without being initialized. This code is several years old and premusably works fine so this can't be a very serious bug. But it's easy enough to silence the warning. If "area_free" is false at the end of the function then we return -ENOMEM.
