svn commit: r198079 - head/sys/boot/i386/zfsboot

[John Baldwin]

Author: jhb

New Revision: 198079
URL: http://svn.freebsd.org/changeset/base/198079

Log:
  Use zfs_read() instead of xfsread() to read /boot.config.  xfsread() fails
  short read requests, so the result was that a /boot.config smaller than 512
  bytes was ignored.  boot2 uses fsread() instead of xfsread() to read
  /boot.config already, so this makes zfsboot more like boot2.
