[PATCH] update filesystems for new delete_inode behavior

Update the file systems in fs/ implementing a delete_inode() callback to
call truncate_inode_pages().  One implementation note: In developing this
patch I put the calls to truncate_inode_pages() at the very top of those
filesystems delete_inode() callbacks in order to retain the previous
behavior.  I'm guessing that some of those could probably be optimized.
