[Cbe-oss-dev] [PATCH 2/3] libspe2: Fix scmctl buffer type

[D. Herrendoerfer]

This patch fixes the declaration of the shmctl buffer parameter
which was a declared to be in PPE memory before.
This function is part of a set that is disabled at the moment
and may be removed in the future. But nonetheless it should
be correct.
