NFS: call nfs_wb_all() only on regular files
It looks like nfs_setattr() and nfs_rename() also need to test whether the
target is a regular file before calling nfs_wb_all()...
It isn't technically needed since the version of nfs_wb_all() that exists
on 2.6.16 should be safe to call on non-regular files (it will be a no-op).
However it is a useful optimisation.
