RISC-V updates for v6.18-rc5

Some RISC-V updates for v6.18-rc5, including:

- A fix to disable KASAN checks while walking a non-current task's
  stackframe (following x86)

- A fix for a kvrealloc()-related memory leak in
  module_frob_arch_sections()

- Two replacements of strcpy() with strscpy()

- A change to use the RISC-V .insn assembler directive when possible
  to assemble instructions from hex opcodes

- Some low-impact fixes in the ptdump code and kprobes test code
