[Skiboot] [PATCH] libflash: Fix pflash -i

[Michael Neuling]

pflash -i is currently broken due to this commit

  commit 602dee4505cd0ceb5b69f056ec403f982b585791
  Author: Cyril Bur <cyril.bur at au1.ibm.com>
  libflash/libffs: Rework libffs

It's output doesn't correctly detect the last partition and continues
printing forever.

This fixes it by returning null when we don't find a partition in
ffs_get_part().
