riscv: kprobes: Remove redundant kprobe_step_ctx
Inspired by commit ba090f9cafd5 ("arm64: kprobes: Remove redundant
kprobe_step_ctx"), the ss_pending and match_addr of kprobe_step_ctx
are redundant because those can be replaced by KPROBE_HIT_SS and
&cur_kprobe->ainsn.api.insn[0] + GET_INSN_LENGTH(cur->opcode)
respectively.
Remove the kprobe_step_ctx to simplify the code.
