    jfs: Fix early release of acl in jfs_get_acl
    
    BugLink: http://bugs.launchpad.net/ubuntu/+bug/396780
    
    Commit 073aaa1b142461d91f83da66db1184d7c1b1edea "helpers for acl
    caching + switch to those" introduced new helper functions for
    acl handling but seems to have introduced a regression for jfs as
    the acl is released before returning it to the caller, instead of
    leaving this for the caller to do.
    This causes the acl object to be used after freeing it, leading
    to kernel panics in completely different places.
    
    Thanks to Christophe Dumez for reporting and bisecting into this.
