sh: kprobes: Remove unused variables in kprobe_exceptions_notify()
kbuild reports the following warning:
arch/sh/kernel/kprobes.c: In function 'kprobe_exceptions_notify':
>> arch/sh/kernel/kprobes.c:412:24: warning: variable 'p' set but not used [-Wunused-but-set-variable]
412 | struct kprobe *p = NULL;
| ^
The variable 'p' is indeed unused since the commit fa5a24b16f94
("sh/kprobes: Don't call the ->break_handler() in SH kprobes code")
Remove that variable along with 'kprobe_opcode_t *addr' which also
becomes unused after 'p' is removed.
