[POWERPC] cell: fix spurious false return from spu_trap_data_{map,seg}
At present, the __spufs_trap_data_map and __spu_trap_data_seq functions exit if spu->flags has the SPU_CONTEXT_SWITCH_ACTIVE set. This was resulting in suprious returns from these functions, as they may be legitimately called when we have this bit set. We only use it in these two sanity checks, so this change removes the flag completely. This fixes hangs in the page-fault path of SPE apps.
