drm/ofdrm: Preallocate format-conversion buffer in atomic_check

Browse source

Preallocate the format-conversion state's storage in the plane's
atomic_check function if a format conversion is necessary. Allows
the update to fail if no memory is available. Avoids the same
allocation within atomic_update, which may not fail.
