Subject: [PATCH 2/2] device: rust: change the name function

This function increments the refcount by this command
"bindings::get_device(prt)"
This can be confused because the function Arc::from_raw() from
standard library, doesn't
increment the refcount.
Then, this function "Device::from_raw()" will be renamed for don't
make confusion
in the future.
