[PATCH] fix intermezzo compile failure

Intermezzo has some strange, broken code trying to deal with extended
attributes and and ACLs.  Fortunately the xattr code is hidden under
a config option that's never set, but the ACL code is enabled by
CONFIG_POSIX_ACL that's se by ext2/ext3 and jfs now.  Change it to
#if 0 to get intermezzo compiling again.
