xfs_mdrestore: Don't rewind source file stream
Today, xfs_mdrestore from stdin will fail if the -i flag is
specified, because it attempts to rewind the stream after
the initial read of the metablock. This fails, and
results in an abort with "specified file is not a metadata
dump."
Read the metablock exactly once in main(), validate the magic,
print informational flags if requested, and then pass it to
perform_restore() which will then continue the restore process.
