Yong-Xuan Wang 625a90b569 riscv: signal: fix signal frame size ...

commit aa49bc2ca8 upstream.

The signal context of certain RISC-V extensions will be appended after
struct __riscv_extra_ext_header, which already includes an empty context
header. Therefore, there is no need to preserve a separate hdr for the
END of signal context.

Fixes: 8ee0b41898 ("riscv: signal: Add sigcontext save/restore for vector")
