Use member value of connectTimeout or loginTimeout directly

Instead of making a local copy of connectTimeout and loginTimeout
use the value directly on the object like: &self->connectTimeout

I am weary of doing this because I've had issues in the past with
creating a pointer from a member variable and it is just my own
lack of knowledge of C/C++ that makes me feel this way. However,
in use this way it does not cause an error assertion in FreeTDS
Readability for getting the address of members
