Log Message:
ppp: remove ioctls that never worked and crash the kernel

Remove vestigial bits of PPP HDLC support that never worked on netbsd.
The TIOCRCVFRAME ioctl was apparently intended to be called only from
within the kernel, but nothing prevents user code from calling this ioctl
and crashing the kernel.
