Revert "media: tuners: fix error return code of hybrid_tuner_request_state()"

commit e25cc4be4616fcf5689622b3226d648aab253cdb upstream.

This reverts commit b9302fa7ed979e84b454e4ca92192cf485a4ed41.

As Fedor Pchelkin pointed out, this commit violates the
convention of using the macro return value, which causes errors.
For example, in functions tda18271_attach(), xc5000_attach(),
simple_tuner_attach().
