vfs catia: Fix the double translation that was happening with createfile and open.

Since the catia translation is implemented for open, it should not
also be done in createfile.  By removing createfile from catia,
translation is now done correctly for the primary open path.

In order to support systems that have custom createfile
implementations that don't eventually call SMB_VFS_OPEN,
SMB_VFS_TRANSLATE_NAME has been expanded to take an additional
argument that specifies direction.
