[PATCH] xfs_repair: don't indicate dirtiness if FSGEOMETRY fails

[Eric Sandeen <sandeen@redhat.com>]

Today, pointing repair at an image hosted on a non-xfs
filesystem will result in a XFS_IOC_FSGEOMETRY_V1 failure,
but repair generally proceeds without further problems.

However, calling do_warn() sets fs_is_dirty to 1, so
xfs_repair -n exits with non-zero status, indicating
corruption.  This is incorrect.

Change the message to use do_log so that it does not
incorrectly indicate corruption.
