samples: rust: fix endianness issue in rust_driver_pci
commit e2f1081ca8f18c146e8f928486deac61eca2b517 upstream.
MMIO backend of PCI Bar always assumes little-endian devices and
will convert to CPU endianness automatically. Remove the u32::from_le
conversion which would cause a bug on big-endian machines.
