Made Ip::Address::fromHost() handle nil pointers after fd9c47d. (#25)

No functionality changes expected. Nobody was passing nil pointers to
this code before or after fd9c47d AFAICT, but now that this code is
exposed as a public method, it must handle nil pointers.

Detected by Coverity Scan. Issue 1415049 (FORWARD_NULL).
