e2fsprogs: fix ptest bug for second running

At second running, there are four new failed case:
  d_loaddump f_bigalloc_badinode f_bigalloc_orphan_list f_dup_resize

The test_data.tmp is necessary, but it is deleted by run-ptest.
So it should be restored after testing.

It is a backport for
  http://cgit.openembedded.org/openembedded-core/commit/?h=master-next&id=d0d08dd9a8a179e25b9cfcbac696c1d212a1910c
It should be deleted after yocto version up.
