net: dsa: qca8k: fix an endian bug in qca8k_get_ethtool_stats()

Browse source

The "hi" variable is a u64 but the qca8k_read() writes to the top 32
bits of it.  That will work on little endian systems but it's a bit
subtle.  It's cleaner to make declare "hi" as a u32.  We will still need
to cast it when we shift it later on in the function but that's fine.
