#186 7i Version, wrong AVP value for hac_test

[Anonymous]

In current Mobile IPv4 test case implementation , "123.4.5.011" and "123.4.5.067" are hard coded IP address. It is fine for test use. There
are two error here:

1. 011 and 067 are not qualified IP string; it should be changed to 11 and 67.

2. These IPv4 string themselves are directly copied into final AVP value field. It is not the right behavior. The final AVP value field should be 4 byets long unsigned integer.
