Remount MDT as ZFS:

[root@lumgr1 mdt1]# getfattr -m - ROOT/f.conf-sanity.61 
# file: ROOT/f.conf-sanity.61
trusted.big
trusted.big
trusted.link
trusted.lma
trusted.lov

Looking at the wireshark dump of the traffic between the MDT and the Client, it appears that the trusted.big xattr is actually created twice on the MDT (judging by the fact that listxattr returns it twice from the MDT). Thus causing the "Protocol error" on the client.
