[PATCH] relayfs: use generic_ip for private data

Use inode->u.generic_ip instead of relayfs_inode_info to store pointer to user
data.  Clients using relayfs_file_create() to create their own files would
probably more expect their data to be stored in generic_ip; we also intend in
the next set of patches to get rid of relayfs-specific stuff in the file
operations, so we might as well do it here.
