Yang Shi df512b40e3 arm64: kprobes: check the return value of set_memory_rox() ...

[ Upstream commit 0ec364c0c9 ]

Since commit a166563e7e ("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.
