arm64: kprobes: call set_memory_rox() for kprobe page

Browse source

commit 195a1b7d83 upstream.

The kprobe page is allocated by execmem allocator with ROX permission.
It needs to call set_memory_rox() to set proper permission for the
direct map too. It was missed.

Fixes: 10d5e97c1b ("arm64: use PAGE_KERNEL_ROX directly in alloc_insn_page")
