   rust: i2c: fix I2cAdapter refcounts double increment (2026-06-06

rust: i2c: fix I2cAdapter refcount double increment

A single bugfix for the Rust I2C abstractions, targeting 7.1.

`I2cAdapter::get` calls `i2c_get_adapter()` which returns a pointer with
an already-incremented refcount. The code then converts the raw pointer to
an `ARef` via `.into()`, which calls `inc_ref()` again through the
`From<&T> for ARef<T>` impl — resulting in a leaked device and module
reference on every call.

The fix uses `ARef::from_raw()` instead, which takes ownership of the
existing refcount without incrementing it.
