Since commita166563e7e("arm64: mm: support large block mapping when rodata=full"), __change_memory_common has more chance to fail due to memory allocation failure when splitting page table. So check the return value of set_memory_rox(), then bail out if it fails otherwise we may have RW memory mapping for kprobes insn page.
