net: sparx5: fix handling uneven length packets in manual extraction
Packets that are not of length divisible by 4 (e.g. 77, 78, 79) would
have the checksum included up to next multiple of 4 (a 77 bytes packet
would have 3 bytes of ethernet checksum included). The check for the
value expects it in host (Little) endian.
Fixes: f3cad2611a77 ("net: sparx5: add hostmode with phylink support")
