Brian Barrett 480ffd3045 Fix issue that came up with testing some LANL romio applications.
MPI_FILE_GET_INFO should return the info currently in use, not the one
used to create the file handle.  ROMIO adds a bunch of keys, so you can
create a file handle with MPI_INFO_NULL and have MPI_FILE_GET_INFO return
something totatlly different.

This commit was SVN r10312.
