General: Avoid early initialization of variable in get_bloginfo().

This is a very minor, yet simple performance optimization in a commonly called function, avoiding unnecessary initialization of the `$url` variable when it may not be needed. The conditional is simple enough to not use a variable altogether.

Props Cybr, swissspidy.
Fixes #59450.
