Xin LI 74ec0afcc7 Correct two bugs that may result in incorrect CBCP response for
administrator specified number.

The implementation in our version transmits extra zero byte that is a
violation of the Microsoft PPP Callback Control Protocol section 3.2[1].
This can lead to incorrect behavior on certain devices, as reported
in bin/50613.

Confirmed with:	cbcp.c in ppp's cvs, rev. 1.4 and 1.15 [2]
