i2c: core: remove outdated DEBUG output

The usefulness of this debug output is questionable. It covers only direct i2c_transfer calls and no SMBUS calls, neither direct nor emulated ones. And the latter one is largely used in the kernel, so a lot of stuff is missed. False positives are also generated in case the locking later fails. Also, we have a proper tracing mechanism for all these kinds of transfers in place for years now. Remove this old one.
