riscv: kprobes: Fix build error when MMU=n
lkp reported a randconfig failure:
arch/riscv/kernel/probes/kprobes.c:90:22: error: use of undeclared identifier 'PAGE_KERNEL_READ_EXEC'
We implemented the alloc_insn_page() to allocate PAGE_KERNEL_READ_EXEC
page for kprobes insn page for STRICT_MODULE_RWX. But if MMU=n, we
should fall back to the generic weak alloc_insn_page() by generic
kprobe subsystem.
Fixes: cdd1b2bd358f ("riscv: kprobes: Implement alloc_insn_page()")
