[PATCH] rxrpc/proc: size address buffers for %pISpc output

[Pengpeng Hou]

Hi,

Thanks for confirming that.

That is very helpful. It matches the current-tree ISATAP case in
lib/vsprintf.c and confirms that the formatter ends up writing 51 bytes
including the trailing NUL into the existing 50-byte stack buffer.

I'll resend the patch with the changelog corrected to frame the proof
around the ISATAP case explicitly.

Thanks,
Pengpeng
