[PATCH] powerpc/ps3: Fix failure paths in ps3_create_spu()

ps3_destroy_spu() expects the logical SPE to be constructed and enabled
successfully. However, ps3_create_spu() calls ps3_destroy_spu() when
either construct_spu() or enable_spu() failed.
Only free spu->pdata when construct_spu() fails. If construct_spu()
succeeded but enable_spu() fails, destruct the logical SPE before
freeing spu->pdata.
