arm64: kprobes: Remove redundant kprobe_step_ctx
The kprobe_step_ctx (kcb->ss_ctx) has ss_pending and match_addr, but those are redundant because those can be replaced by KPROBE_HIT_SS and &cur_kprobe->ainsn.api.insn[1] respectively. To simplify the code, remove the kprobe_step_ctx. Signed-off-by:Masami Hiramatsu <mhiramat@kernel.org> Reviewed-by:
