[PATCH 4/5] perf intel-pt: Packet splitting can happen only on 32-bit

[Adrian Hunter]

Data is copied when the trace is stopped, so packets are never split
between buffers except when processing if the buffer cannot fit in the
address space which can only happen on 32-bit systems. Change the logic to
reflect that.
