Andreas Kling acebc9beaf Ext2FS: Use if-with-initializer a lot more ...

This pattern felt really cluttery:

auto result = something();
if (result.is_error())
    return result;

Since it leaves "result" lying around in the no-error case.
Let's use some C++17 if initializer expressions to improve this:

if (auto result = something(); result.is_error())
    return result;

Now the "result" goes out of scope if we don't need it anymore.
This is doubly nice since we're also free to reuse the "result"
name later in the same function.
