NFS: nfs_wcc_update_inode() should set nfsi->attr_gencount

commit 27dc1cd3ad9300f81e1219e5fc305d91d85353f8 upstream.

If the call to nfs_wcc_update_inode() results in an attribute update, we
need to ensure that the inode's attr_gencount gets bumped too, otherwise
we are not protected against races with other GETATTR calls.
