Fixes gh-369 - Assignment in test condition

Fix an assignment that was intended to be a comparison in
CLazyFileIOCache::removeFile. As far as I can tell this would not cause
any issues in current usage of this function (we got lucky...).

Also reformatted the function to current coding standards and renamed
a confusing variable name.
