Can you try reverting this change:

New Revision: 221177
URL: http://svn.freebsd.org/changeset/base/221177

  Due to space constraints, the UFS boot2 and boot1 use an evil hack where
  boot2 calls back into boot1 to perform disk reads.  The ZFS MBR boot blocks
  do not have the same space constraints, so remove this hack for ZFS.
  While here, remove commented out code to support C/H/S addressing from
  zfsldr.  The ZFS and GPT bootstraps always just use EDD LBA addressing.
  MFC after:    2 weeks
