rust: io: fix unused Flags::from_raw warning without CONFIG_PCI

Currently, `Flags::from_raw()` is only used by
`pci::Device::resource_flags()`, so rustc errors (with CONFIG_WERROR)
saying that it is never used when `CONFIG_PCI` is disabled.

    error: associated function `from_raw` is never used
       --> rust/kernel/io/resource.rs:240:25

`Resource::flags()` also converts the raw `flags` field to `Flags` and is
built in every config, so the easiest way to get rid of this error is
to just use it there too.
