[PATCH] fuse: clean up dead code related to nfs exporting 

Remove last remains of NFS exportability support.

The code is actually buggy (as reported by Akshat Aranya), since 'alias'
will be leaked if it's non-null and alias->d_flags has DCACHE_DISCONNECTED.

This is not an active bug, since there will never be any disconnected
dentries.  But it's better to get rid of the unnecessary complexity anyway.
