i2c: rust: mark I2cAdapter methods as inline

Browse Source 
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.
