net: jme.c rxdesc.flags is __le16, other missing endian swaps 

This is the minimal patch to fix endian mismatches.  These are
probably bugs on big-endian arches, noops on little endian.

jme_rxsum_ok could be improved to directly take a __le16 and
change all of the masks/sets to be in little-endian, but
has not been done here to keep the patch small.
