Patch for 'zfs send -R' core dump (pr bin/130105)

The following patch to

  /usr/src/sys/cddl/contrib/opensolaris/common/zfs/zfs_prop.c

seems to keep 'zfs send -R' from dumping core.  I've only been able to
test sending the stream to /dev/null or a file, I'm still setting up a
pool to do the receiving.

This is based on a bit of gdb debugging and a thread from zfs-fuse:
