simpleperf: fix ReadAuxDataFromKernelBuffer. Record buffer is a circular buffer. AllocWriteSpace() allocates a continuous space from it. If alloc_size > record_buffer_critical_level, AllocWriteSpace(alloc_size) may fail even when free_size >= alloc_size + critical_level. So we need to handle that situation. Bug: none Test: run simpleperf_unit_test Change-Id: I3fc82162fb00bde644086b4e277e631434fad304
