i2c: rust: mark I2cAdapter methods as inline

A single cleanup for the Rust I2C abstractions, targeting 7.3.

`I2cAdapter::get`, `inc_ref`, and `dec_ref` are trivial wrappers around
`i2c_get_adapter`/`i2c_put_adapter` and were showing up as their own
symbols in the build. Mark them `#[inline]` so they get folded into
their callers instead.
