Andre Detsch 61b36fc1f7 [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.
