Jiexun Wang d68c74f3b2 RISC-V: Fix wrong use of CONFIG_HAVE_SOFTIRQ_ON_OWN_STACK 
commit 07a2766575 upstream.

If configuration options SOFTIRQ_ON_OWN_STACK and PREEMPT_RT
are enabled simultaneously under RISC-V architecture,
it will result in a compilation failure:

arch/riscv/kernel/irq.c:64:6: error: redefinition of 'do_softirq_own_stack'
   64 | void do_softirq_own_stack(void)
      |      ^~~~~~~~~~~~~~~~~~~~
In file included from ./arch/riscv/include/generated/asm/softirq_stack.h:1,
                 from arch/riscv/kernel/irq.c:15:
./include/asm-generic/softirq_stack.h:8:20: note: previous definition of 'do_softirq_own_stack' was here
    8 | static inline void do_softirq_own_stack(void)
      |                    ^~~~~~~~~~~~~~~~~~~~

After changing CONFIG_HAVE_SOFTIRQ_ON_OWN_STACK to CONFIG_SOFTIRQ_ON_OWN_STACK,
compilation can be successful.

Fixes: dd69d07a5a ("riscv: stack: Support HAVE_SOFTIRQ_ON_OWN_STACK")
