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.
