powerpc/spufs: add a missing mutex_unlock
commit 6747c2ee8abf749e63fee8cd01a9ee293e6a4247 upstream.
A mutex_unlock(&gang->aff_mutex) in spufs_create_context() is missing
in case spufs_context_open() fails. As a result, spu_create syscall
and spu_get_idle() may block.
This patch adds the mutex_unlock.
